PASTURE PLUS PERFORMS LONG TERM 0-29 weeks
Conclusion: Pasture Plus and Pasture Grow both produced long term changes in both pasture volume and quality. This trial is living proof of the compounding concept Biohelp products exhibit.

Key Observations: This trial further supports other trial we have done and shows clearly that both Pasture Plus and Pasture Grow are better than Urea long term and do not show the typical downward response of normal fertilisers. Urea gave adequate short term growth but is poor after that. In the first 5 weeks urea produced 5% (440Kg/Ha) more fresh weight but less dry matter per Hectare. Pasture Plus and Pasture Grow created soil changes that maintained superior growth for a long period of time. Previous trials with sunny weather conditions showed Pasture Grow could match 100KgUrea/Ha in short term growth, This trial indicates that cold cloudy weather could limit the short term pasture response when compared to Urea. However long term growth was vastly superior.

Aim: most granular NPK fertilizers boost grass performance for 4 months at best. This trial was established to test the longevity of Pasture Plus and Pasture Grow, and we took another opportunity to test it short term against Urea.  On many sheep properties urea is currently being used to boost a Hay or Silage paddock. Pasture Plus proved a far better choice. Herbage tests were taken after 7 months to see if the product with the best growth performance would also improve the feed quality against the untreated area.

Herbage quality. Pasture Plus gave fractionally better quality pasture across all nutrients with soluble sugar being the most significant change (up 40%) in the pasture. Seven months after treatment Pasture Plus was producing better quality feed.

Weather conditions:
Overall growth throughout the trial was poor due to weather. It snowed 3 days after setting up the trial and was cloudy for the first 5 weeks of growth. For the rest of the trial it was dry and hot. The soils dried out very quickly. This continued for the remainder of the trial.

Treatment: Pasture Grow 4.5 L/Ha . Pasture Plus 20L/Ha, Urea 80 Kg/Ha

Trial details: (p<0.05) 5 replicates. Samples were Cut and dried. Paddock History: Re-sown in ryegrass in Feb 2004 sown with 200Kg Crop15. Soil test at start of trial was CEC16 Sulphate SO4 2; Olsen P 32 ; BS 76% - Ca 57%, Mg11%, K 5.5%, Na 2.0%

PASTURE PLUS formula 2 VS 80 KG UREA - DRY LAND
“Which product do I boost my farm with this Autumn and is it to late to apply?.”

With the drought expected to go into late Autumn many farmers are wondering how they will feed their stock through winter. The tendency might be to put on Urea for a quick fix. This trial showed that Pasture Plus Formula 2 is a better alternative in almost exactly the same conditions that might occur this season. Last Autumn I set up a replicated trial on shallow dry land soil with low soil nutrients. The pasture species were browntop, cocksfoot, goose grass, and sub clover. Plots were treated in March, and cut for hay in November. I had planned on taking an 8 week measurement but no rain fell until winter so no autumn growth occurred. Winter was very cold so no growth occurred there either. So, we had to wait until spring to get enough grass to measure. Pasture Plus Formula 2 increased production by 6% or 328kgDM/Ha (cost 18cents/kgextra dry matter). 80 kg Urea yielded -3% or –110kgDM/Ha with an economic loss overall. This trial supported others I have done indicating that urea actually has a negative impact on grass growth when measured past 3 months. In stark contrast Biohelp products (due to positive soil development ) create a long term positive change in grass production regardless of the short term response (which in this trial was negligible for all products due to dry weather).




FIELD DATA SUPPORTS SCIENTIFIC TRIALS;
Field trials:
To us the purpose of field trials is to establish if the trends measured in smaller scientific trials are carried through into the field under normal farming conditions. Since November 2007 we have had a number of clients trailing our product against others. One specialist liquid spray contractor with 15 years experience has done the following trials. We have removed the names of the liquid products for courtesy reasons, but we can assure they are what the contractor considered the best liquids he has used. One biological based product sourced out of the Waikato region was also compared. The contractor oversaw the measuring in most cases. Typically a 2Ha area is covered and we go out and measure the results prior to their next grazing or silage cut. With the dry conditions in Autumn 2008 year many rotations were short and we have measured after less days growth than our scientific trials have been done at. When the paddock is consistent we use a lawnmower leaving the grass clippings behind so the farmer can go and measure them for himself if he wishes. He can see where we have cut the paddock and can determine for himself if we have chosen a fair representative of each side. Ideally the farmer should come with us, but the reality is most are too busy to do this. When paddocks are inconsistent we use an electronic probe which is a device that’s measures the overall pasture cover and is OK for comparison purposes under most situations.
These field trials are not scientific, but they do show consistent trends that support our scientific trials presented on our website. They also indicate why we are prepared to back Pasture Plus at 20L/Ha against any other product in the market.

West Southland:
Farmer 1 Pasture Plus against 75kgUrea
Southland last March, we compared Pasture Plus against 75kgUrea at 4 weeks across 8 separate paddocks. At 4 weeks with favourable growing conditions Pasture Plus was 13% in dry matter ahead of Urea (typically our trials show 80kgUrea produces 6-15% more dry matter over this period depending on the weather conditions). The soils were 1 degree warmer and herbage tests showed a big increase in the energy levels of the Pasture Plus treated grass (Urea 9.7MJME/Kg vs Pasture Plus 11.4MJME/Kg). Lifting the energy levels in the grass generally means less feed is required to maintain the same body weight.
So whether you are facing dry or wet conditions Pasture Plus is your best choice this Autumn. Pasture Plus always delivers an economic return even if weather conditions delay when this will occur. There is also no withholding period for Pasture Plus. It can be grazed straight away and will still produce great regrowth. On the ground (which includes a spray contractor) its the same price as 80kgUrea/Ha (incl freight and spreading). It can be applied through any spray boom, nozzle jet system or irrigator.
Note:1. I have assumed the same dry matter trend occurred as we have experienced in previous trial work and have applied these to trials cut with the lawn mower.
Note 2. we have estimated over all growth by eye to give some idea of the percentage increase in dry matter production.

Culverden:
Farm 1: PPF2 20L/Ha was compared against >60KgUrea/Ha.
Light soils young grass. The paddock was treated and cut for silage. 10 days later the regrowth was measured prior to the cows going into graze. We cut and weighed the following control 825kgFW/Ha; Urea 972kgFW/Ha (+17%); Pasture Plus 1136KgFW/Ha (+37%). Assuming DM% of control 30%, Urea 28%. PPF2 29%. PPF2 increased pasture growth 8.2KgDM/day or 33% and Urea a mere 2.5Kg/day.

Rangiora Area:
Farm 1: Pasture Plus was compared against 80Kg Urea
Heavy soil with waterlogging problem.
Dry for first 3 weeks then 6 inches of rain and paddock measured with probe 14 days after rain and 5 weeks after applying. Urea 2257KgDM/Ha Pasture Plus 2854KgDM/Ha(+26% or 17KgDM/day over and above the Urea response. Assuming residual cover of 1500KgDM/Ha then Urea averaged 21KgDM/day and PPF2 38KgDM/day an increase of 80%. Before the rain Pasture Plus looked to be visually ahead although the paddock was extremely varied in cover. After the rain Urea treated grass looked significantly ahead (we were expecting 20-30%) however there was no guts in the grass and it measured up significantly lower.

Farm 2: Another biological (AB)used against Pasture Plus Waikuku
Heavy soils . Long history of liquid fertilisers with good grass production. Other biological had been applied to the whole farm in early Spring. 3 paddocks were treated with a control left in only 1 paddock . Paddocks were ready to be cut for silage. Cut 14 January 2008
First paddock yielded control 3327kgDM/Ha AB 3871KgDM/Ha (+16% or +18KgDM/day) Pasture Plus 4204kgDM/Ha (26% or + 29KgDM/day). Assuming start cover of 1500Kg/Ha, then control grew at 58KgDM/Ha/day and PPF2 at 88kgDM/Ha/day an increase of 51%.
Second paddock . AB 3807KgDM/Ha Pasture Plus 4108kgDM/Ha (+ 8% or 10kgDM/day above AB.
We had a consistent trend Pasture Plus was 10% and 8% above AB. There was no visual difference in grass height or colour between any treatments and the control. However the lawn mower struggled to cut Pasture Plus treatments. PPF2 had been applied to 70 Ha of which most was cut for silage. The farmer commented that he had never had a second silage cut yield as well as the first and he ran out of space in the pit for the first time ever. He is also commenting that he has never had so much Autumn grass.

Farm 3: PPF2 20L/Ha vs a high analysis liquid fert (LFHA) with seaweed base at 15L/Ha Sefton:
Two paddocks were treated at the end of summer and prior to drought breaking rains. Both products were applied in 25 degree heat and to bone dry pastures. One was grazed prior to the rains Client noticed stock ate PPF2 treatment 4cm lower than both control and high analysis N. One week after applying 6 inches of rain fell. Measurements were taken 10 days later on both paddocks and 4 weeks later on the ungrazed paddock.
Grazed paddock 10 days after rain and grazing had stopped:
Control 1174kg/Ha LFHA @15L/Ha 1281kg/Ha (+9%) Pasture Plus 1308kg/Ha (+11.5% or 13.4KgDM/day ).
Ungrazed paddock 10 days after rain:
Control 1568 Kg/Ha LFHA 1449Kg/Ha(-8%) PPF2 1688Kg/Ha (+7% or 12KgDM/day). Assuming an initial cover of 1300KgDM/Ha then control was growing at 26KgDM/Ha/day and PPF2 at 38.8KgDM/Ha/day an increase of 50%.
30 days after rain LFHA was still negative and PPF2 continued to grow at 12KgDM/Ha over the control thus producing around 400KgkGDM extra over the 30days prior to grazing.

These paddocks showed similar pasture response to our longer term scientific grass trial. Here we got a 7 % response after rain and in our long term trial with similar grass species we got 6%.

Farm 4: PPF2 vs Liquid fert (LF) seaweed base Fernside:
21 days growth measured against LF : First paddock PPF2 ahead by 200kgDM/Ha. (3202kgDM/Ha vs 2988 or +10KgDM/day). Next paddock PPF2 ahead by 478KgDM/Ha (3815KgDM vs 3337KgDM/Ha or +22KgDM/day). Assuming starting point of 2000KgDM/Ha then pasture growth was at 63KgDM/Ha/day with LF and 86KGDM/Ha/day with PPF2 an increase of 37%. The farmer estimated the overall paddock growth at around 60KgDM/day, based off top leaf growth. The most noteable difference between the 2 treatments was the PPF2 treated grass was harder to walk through; providing more resistance against your legs.

Farm 5: PPF2 compared against 100Kg Urea/Ha. Waikuku:
There was no difference. Pasture Plus Formula 2 grew as much as 100Kg/Ha of Urea. The Urea treatment cost another $20/Ha. Soil had obvious imbalances in the nitrogen fixing organisms made evident by the tall Urine patches. I have found that these soil conditions often create an imbalance in the ratio of Nitrates to ammonium in the soil and acts as a short term leveller when comparing Pasture Plus Formula 2 and Urea. Applying Urea gives a good visual response but will further the problem creating poorer long term growth. When soils are like this the best solution is to use a little Urea and Pasture Plus and Microlife together for the first couple of applications. This helps rebalance the nitrogen fixing organisms and gives sensational growth responses.

Selwyn District:
Farm 1: PPF2 compared versus Liquid fert (fish base)20L+10KgN liquid. 29 Oct 2008 Norwood:
Liquid N was applied at 40L/Ha delivering 10kgN/Ha. Measured with an electronic probe 20 days after treatment. Pasture Plus Formula 2 had grown an extra 370 kgDM/Ha and liquid fert +N 122KgDM/Ha. Control 2467kgDM/Ha ; LF+liquidN 2589KgDM/Ha ; PPF2 2837kgDM/Ha. From a distance there was no visual difference. Walking through it PPF2 was doing better in the spaces between the urine patches - Slightly thicker and a little taller. Urine patches were growing very well indicating a potential problem of imbalances in the nitrogen fixing organisms. Assuming start cover of 1500Kg/Ha, then control grew at 48KgDM/Ha/day, fish+liquidN at 54kgDM/Ha/day (up12%) and PPF2 67kgDM/Ha/day at an increase of 45%.

Comment: This is a typical response. PPF2 will continue to grow extra DM for many months to come. After 20 days you already have an economic response at 17cents/KgDM. This will end up at about 4cents/kgDM over the ensuing months.

West Coast:
Field trials: In Autumn 2008 a spray applicator treated half paddocks on several different properties in the Maruia Valley Applied 2 April. Urea was applied at 70Kg/Ha being the same price on the ground as Pasture Plus at this date. With the dry conditions this year many rotations have been very short and we have measured after less days growth than our scientific trials have been done at. An electronic electronic probe measured the overall pasture cover after 20 days.

Maruia Valley:
Farm 1 Pasture Plus vs 120kg ammonium sulphate.
Soil had real problems - grass pulled out by grazing because roots were so shallow.
Ungrazed after 3 weeks. Ammonium sulphate 2850 kgDM/Ha; Pasture Plus 2909 KgDM/Ha (+2%). If ammonium sulphate gave a typical 8-10% increase over untreated pasture then a further 2% is a 20-25% improvement.
Grazed pasture with 10 days regrowth. Ammonium Sulphate 2000kgDM/Ha Pasture Plus 2282KgDM/Ha (+14%). Assuming initial pasture cover of 1600 then Ammonium Sulphate is growing at 40KgDM/day and PPF2 at 68KgDM/Day, an increase of 70%.

Farm 2 Pasture Plus vs 70Kg/Ha Urea
Grazed for 1-2 days by cattle : The average of 3 passes across paddock showed Pasture Plus 2714kgDM/Ha Urea 2538 DMkg/Ha head by 176KgDM or 9KgDM/day. I guess the average pasture growth over the 20 days for urea was around 50kgDM/day and 60kgDM/day for Pasture Plus.

Farm 3: Pasture Plus vs 70Kg/Ha Urea
This farm receives about 200units N/Ha/Yr following the cows on every round. It also received lime on the same day as we applied Pasture Plus. I was uncertain if this would affect the usual results. This paddock was in poor health overall and the overall growth was very poor over the 20 days.
Pasture Plus measured 2003kgDM/Ha and Urea 1775kgDM/Ha. An advantage of 228kgDM/Ha or an extra 10.2KgDM/day. I estimate the overall paddock growth with Urea to be around 20-25KgDM/Day over this 20 day period. PPF2 increased growth around 50%.
The result was consistent with other trials on paddocks in poor health.

Farm 4: Pasture Plus vs 70Kg/Ha Urea
PPF2 was trailed against Urea on 2 quite different paddocks next to each other.
Paddock 1: This was a poor paddock with obvious signs of ill health. After 20 days PPF2 measured 1793KgDM/Ha and Urea 1625KgDM/Ha. After 20 days PPF2 was ahead by 168KgDM/Ha or 8.4 kgDM/day. My guess is this paddock in spite of Urea usage had grown only 10KgDM/Ha/day. PPF2 increased growth around 80%
Paddock 2: 2 measurements were made to lift the urea result closer to the PPF2 measurement. PPF2 average 2234 KgDM/Ha KG ( 2201 + 2268) and Urea 1677KgDM/Ha (1425+1929). PPF2 after 20 days was ahead by 557KgDM/Ha. This is an increase of 27KgDM/Ha/day. Assuming a starting residual of 1300kgDM/Ha then Urea fed grass was growing an average of 19KgDM/Ha/day. PPF2 was 47kg/day an increase of 245%. I felt this was a realistic difference based off pasture density and plant vigour.

Farm 5: Pasture Plus vs 80Kg/Ha Urea: April 08
This was a sheep farm with a history of 1 Urea dose in Autumn over the last few years.
Paddock 1: 1 - 2yr old pasture coming from crops where very little nitrogen had been applied as fertiliser. Before trailing this paddock I mentioned I was dubious about the result we may get against Urea. The ground felt very dead and I suspected a true lack of soil Nitrogen. I suggested another paddock with a better history be done as well. My hunch was correct. Urea was slightly ahead after 20 days. Urea 1717 KgDM/Ha versus PPF2 1645 kgDM/Ha. A difference of 72kgDM/Ha or 3.6KgDM/day. The growth on both areas was extremely poor less than 10KgDM/day indicating how tired this paddock was. Longer term I expect PPF2 to out grow the Urea, but short term I wasn’t surprised by the result in this particular case. This paddock would benefit a lot from Microlife. By on 16 October 08 the farmer commented that the Pasture Plus treated area was doing much better than the Urea treated side.
Paddock 2: A healthy paddock with no evidence of trouble or nutrient deficiencies.
PPF2 2509KgDM/Ha versus Urea 2004KgDM/Ha. An extra 505KgDM/Ha over 20 days or 25KgDM/day over and above Urea. Assuming starting cover of 1300kgDM/Ha then Urea fed grass grew at 35kgDM/day and PPF2 60kgDM/day an increase of 71% over and above Urea. There was no colour or height difference but PPF2 was notably more difficult to walk through and plant tillers significantly thicker. This was consistent with other results on healthy soils.

Farm 6: Pasture Plus vs 100Kg/Ha Urea 16 Oct 08
This paddock was in poor health overall and the overall growth was very poor over the 28 days. Two readings were done. The farmer was present at measuring. Visual response supported the measured response.
Pasture Plus measured 2265KgDM/Ha and 2041 average 2153 KgDM/Ha Urea 1420 and 1843 average 1631KgDM/Ha. An advantage of 522kgDM/Ha.

Comments:
These measurements have been done short term and I expect Pasture Plus to gain further advantage as time passes and soil changes begin to occur. The Urea will get worse with time. The field data supports the same trends we have observed in our scientific trials available on our website or from your local McDonald Agrifert rep. PPF2 is more than capable of producing significantly more dry matter versus typical dressings of Urea, with the occasional result being the same as 70 -100KgUrea/Ha. The healthier the paddock the bigger the difference. When you look at the consistency of response and the intensity against other products in the market PPF2 is also extremely fairly priced. All the paddock we used would benefit hugely from Microlife for 2 seasons.

The visual response of Urea is often more favourable and at times both the spray contractor and myself thought Urea looked 30% ahead of PPF2. Measurements told us the opposite. PPF2 was substantially ahead of Urea. The results against liquid fertiliser and another biological product set PPF2 apart from the rest of the liquid biostimulants. PPF2 is definitely not another reinvented liquid fertiliser and is definitely not just another biological stimulant. When you look at the consistency of response and the intensity against other products in the market PPF2 is priced as a real bargin.

The trials presented here are conducted by both agricultural scientists and clients. Thus a healthy balance exists between formal well conducted studies and on farm field results. Farmers, scientists and consultants have many different views on the usefulness of trials; objections include, efficacy, independence, and the fact that companies only present the good ones etc. Examples supporting these arguments are easy to find within the agricultural industry.

As a company we plan for the bulk of our sales growth to be through repeat business and word of mouth. Thus, it is in our best interests to present trials which represent the potential our products can deliver on a consistent and reliable basis. Biohelp (NZ) Ltd would like to reassure readers that the trials presented here are accurate, contain no bias, and the results have been consistent.
