Why Cotton Nutrition Needs a Whole-of-Season, Whole-of-Soil Approach

Back Paddock Company — Fri, 09 May 2025 01:26:51 +0000

Cotton growers and agronomists are well aware of the pressure points in-season: picking the right nitrogen strategy, adjusting to weather, managing costs, and avoiding constraints to yield. But when we treat nutrition as a series of isolated decisions rather than part of an integrated soil and crop strategy, we can miss the broader, compounding effects—on […]

Critical nutrient level for cotton plant tissue declines over time.

The critical level in the youngest mature leaf and its petiole typically decreases for N and K as the cotton plant progresses through its phenological stages.

Canopy temperature helps avoid stressed crops at sampling.

One of the variables that can significantly affect the accuracy of plant tissue analysis in cotton is plant stress, particularly plant water stress. Currently, this is avoided by limiting sampling to a particular day in the irrigation cycle or after rain and time of day and with some reference to soil moisture probe readings. With […]

Timing the use of nitrification inhibitor treated N fertilisers in-crop in irrigated cotton

Chris Dowling — Sat, 23 Dec 2023 23:32:44 +0000

The use of efficiency enhancement additives (EEF) in nitrogen fertiliser products in irrigated cotton seems to be on the rise as we experience their benefits, successful use cases and measure successes. EEF technology used in cotton most frequently includes ammonia volatilisation inhibitors, nitrification inhibitors and a combination of both in a single product. While research […]

Why test petioles for nitrate-N?

Chris Dowling — Tue, 19 Dec 2023 05:18:46 +0000

Some advisers have asked, “why have BPC continued to use petiole nitrate-N” in our in-crop cotton N management service? My answers are sometimes a bit long-winded and technical, but the short answer is that “we haven’t been able to find a technology that is able to replicate the responsiveness of tracking nitrate-N from the soil […]

It’s go time for cotton sampling!

Chris Dowling — Fri, 08 Dec 2023 05:12:59 +0000

The first leaf and petiole samples from Moree have been tested through the BPC Cotton Plant Tissue system. Early results are posing questions about the effect of preplant N management on starting levels of plant tissue N, compared to previous seasons and established critical ranges. Of particular interest is the effect of nitrification inhibitors and […]
