Delayed allocation of irrigation water in 2020 resulted in the late preparation of fields for 2020-21 summer crops. As a result, some growers missed an opportunity to address issues or yield-limiting factors.

Growers that have saved yield maps from this, and previous harvests of cotton, rice or corn crops, will likely have information that will highlight areas with underlying soil issues.

Harvest data highlights lower productivity areas which can be limited by one or more of the following; poor soil chemistry, insufficient nutrients through the growing season, issues with soil structure, or poor functioning soil biome.

Soil tests, in conjunction with leaf and tissue tests from prior crops, can identify a range of issues or limiting factors. How you prepare fields for upcoming crops can start addressing these issues.

Calcium balance and low pH are typically addressed with applications of lime and/or gypsum when preparing fields. Incorporating BioAgPhos as a source of sustained-release P not only supports crops through the growing season, but with current high prices for starter fertiliser, it is a lower-cost way to supply part of your crop’s phosphate needs.

BioAgPhos will supply phosphorus for up to three seasons and provides a stable form of phosphate that is released to crops as they require it. BioAgPhos will not leach through soils, while runoff is significantly reduced compared to conventional water-soluble fertilisers. Reducing phosphate losses is financially and environmentally better.

Contact your BioAg representative to review your yield maps and test results, and establish a plan for field preparation.
