Abstract:

Field experiments were conducted in Arizona in 2001 at three locations (Maricopa, Marana, and Safford). The Maricopa and Safford experiments have been conducted for14 consecutive seasons and the Marana site was initiated in 1994. The original purposes of the experiments were to test nitrogen (N) fertilization strategies and to validate and refine N fertilization recommendations for Upland (Gossypium hirsutum L.) and American Pima (G. barbadense L.) cotton. The experiments have each utilized N management tools such as pre-season soil tests for NO₃⁻-N, in-season plant tissue testing (petioles) f

Abstract:

The importance of residual soil nitrogen (N) in the production of upland cotton in Central Arizona has not been adequately studied. A subsurface drip irrigation experiment was conducted at the Maricopa Agricultural Center to examine the effect of residual soil nitrate content on lint yields of upland cotton, and to evaluate the validity of current cotton petiole nitrate interpretations under high yielding conditions. Different levels of water and N fertilizers applied to the plot area in previous years had resulted in a range of residual NO₃-N content ranging from 36 to 166 lbs /acre. Lint yie

Abstract:

Phosphorus (P) is essential to life on Earth and often the limiting nutrient in agricultural systems. P fertilizer is thus an essential resource to maintain food security. In the last half century, agricultural intensification has led to an increase in P fertilizer consumption from 4.6 to 17.5 Tg of P/year to meet rising global food demand. Mineral P (i.e., phosphate rock) is a non-renewable resource in the context of the Anthropocene, and its price is vulnerable to global market fluctuations. Increased efficiency of P use on farms is considered the most effective strategy to conserve P. The s

Abstract:

[Truncated abstract] A greater adoption of stubble retention, minimum-till and no-till farming practices for the purposes of conserving soil, water and fertility requires a greater understanding of the complexity of physical and chemical interactions between the soil and crop residues. There is currently insufficient knowledge to allow reliable predictions of the effects of different residue types in different environments on soil fertility and crop growth, owing to the many residue characteristics and environmental interactions that have been shown to affect decomposition or nutrient release.

The degradation of soil quality due to undesirable farming practices has reached alarming scales in the Eastern Cape and this has had negative repercussions on soil productivity and the environment in general. There is growing evidence that conservation agriculture (CA) practices involving minimal mechanical disturbance, maintaining permanent surface cover and embracing diverse crop rotations increase soil organic carbon (SOC) and therefore has potential to mitigate soil quality deterioration.

What effects would the WTR have on the soil solution composition (and by implication the quality of the groundwater)? 4. Could this material be used to reduce solubility of potential pollutants?

In Vietnam, approximately 1.3 M ha of acacia and eucalypt plantations have been established in the past three decades to supply a growing local and international demand for pulp and sawlog.

There is concern that current practices, i.e. burning harvest residues and only applying a small dose of fertilisers at planting are in part responsible for this situation and need to be changed.
