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 […]

New red imported fire ant requirements for the movement of soil samples

Tom Cowlrick — Thu, 15 Feb 2024 01:18:31 +0000

The following information was circulated by Jeff Kraak Fertilizer Australia and has been reproduced here on their behalf. If you are involved with soil sampling in SE Queensland or around Murwillumbah (NSW), please consider the following information about red imported fire ants. The conditions for sending soil samples from the fire ant infested area to […]

Changes in cotton N status now crops are flowering.

Chris Dowling — Mon, 12 Feb 2024 02:47:27 +0000

While many crops will be past the time when significant N fertiliser rate decisions are likely for this season the petiole N data is some interesting comparisons that can be made between the apparent crop N status of the Northern and Southern crops, and comparisons with trends data from the Dec-Jan period commented on in […]

How long does an N application take to show up in petiole nitrate-N?

Chris Dowling — Fri, 29 Dec 2023 07:00:00 +0000

The nitrification of urea applied in summer is generally not limited by soil temperature or a lack of soil microbial population. This leaves soil water as the main factor limiting its conversion to nitrate-N. Therefore, fertiliser N availability is related to two factors. Too dry for the soil biology to be active in the application […]

Canopy temperature helps avoid stressed crops at sampling.

Chris Dowling — Wed, 27 Dec 2023 06:02:20 +0000

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 […]

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 […]
