– Intelligent Farming Where It Matters!
Precision agriculture is evolving to be one of the most important parts of farming. Growers see variability on their farm every year and they know that it is costing them money. Precision agriculture can also be defined as “site-specific crop management” where the goal is to optimize returns on inputs while preserving resources.
Cavalier Agrow believes that site specific crop management starts in the soil. Variability in the soil is one of the biggest culprits of crop variability. The efficacy of crop protection products will be improved when crop variability is minimized, increasing the return on investment.
iFARM VRx has been designed to address the four “R’s” in nutrient management (the right source, right place, right time and the right rate) taking site-specific crop management to a completely new level. Soil samples are taken from every five acres of a field and analyzed individually by A&L Labs (the most innovative soil lab in Canada). The data then is analyzed where a map of each nutrient in the soil is created (Figure 2 and 3) to visually understand nutrient variability. With unique algorithms, prescriptions maps are created for every nutrient needed in that field that is guaranteed to work in every variable rate capable monitor. With this kind of analysis, you end up with over 1600 potential zones on your field, unlike other more conventional variable rate programs which only offer 3-7 zones.
With this technology, floating in the fall gets a whole new meaning. It is possible to use this prescription map in a floater to variable rate most nutrients (especially nitrogen and sulphur). This leaves more room in your air cart and helps reduce the number of times to fill per field when seeding. You also have the option to variable rate your phosphate and/or potassium based on the soil analysis. Other conventional variable rate programs use satellite imagery which measures the amount of green material in the field. This should correlate to yield, but this method relies on nitrogen only to fix field variability. Variability is definitely not just caused by nitrogen. Countless studies have shown that there are seventeen essential nutrients that can have an influence on yield. iFARM VRx is based on soil tests and the grower has access to over 32 layers of information that can contribute to variability.
With this huge amount of data, correlations can be drawn with yield maps. This is extremely valuable to realize which soil attribute(s) have the biggest influence on yield in that specific field. It makes sense to “fix” the biggest problem first and then move to other less important attributes later. Not all soil attribute issues can be fixed in one year as economics always plays a role in precision agriculture. Now that is precise!
