Reduce Fertilizer and Nitrogen Input
SCIENTISTS at an environmental biotechnology company have developed a biological product that could potentially be used to directly reduce the amount of nitrogen and other fertilisers used by arable farmers. Amnite® A100, created by Stockton-on-Tees-based CBio (Cleveland Biotech), relies on an improved symbiotic relationship between plants and soil microbes - by increasing and improving ...

Spatial variability of the Illinois soil nitrogen test: Implications for sampling in a turfgrass system
Nitrogen fertilization of turfgrass continues to be scrutinized due to environmental concerns. Practices that reduce fertilizer inputs without sacrificing turfgrass quality are needed, but a reliable test of N status in turfgrass is not currently available. The Illinois soil N test has been developed to predict crop response to applied N by measuring the amount of amino sugar N in the soil. Amino ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...

Crop rotation and nitrogen input effects on soil fertility, maize mineral nutrition, yield, and seed composition
Knowledge of complex relationships between soils, crops, and management practices is necessary to develop sustainable agricultural production systems. Objectives were to determine how maize (Zea mays L.) would respond to monoculture (C-C), 2-yr rotation (C-S) with soybean [Glycine max (L.) Merr.], or 4-yr rotation (C-S-W/A-A) with soybean, wheat (Triticum aestivum L.), and alfalfa (Medicago ...

Nitrogen storage with cover crops and nitrogen fertilization in tilled and nontilled soils
Improved crop and N management practices are needed to increase soil N storage so that N fertilization rate and the potential for N leaching can be reduced in tilled and nontilled soils. We examined the influence of cover crops and N fertilization rates on N inputs from cover crops, cotton (Gossypium hirsutum L.) and sorghum [Sorghum bicolor (L.) Moench] and soil total N (STN) content at the 0- ...

NUE Explained: What is a Nutrient Use Efficiency score?
Are you making the most of your soil? Understanding your NUE score is pivotal to understanding not just nitrogen use efficiency, but also your soil’s overall potential. Effectively and efficiently managing inputs is one of the best ways growers can lower operating costs, maintain yield and reduce waste, but with so many factors impacting the production of each bushel, it can ...

Nitrogen-Fixing Bacteria
Opinion piece: sustainability gets supercharged thanks to all-new formulation designed to drive yield As a farmer your job is as simple as it is intensely complex: sustainably produce food to feed the world. A key component of profitable agriculture is using the exact amount of inputs to drive yields. Fertilizer, your largest expense, must be critically timed to achieve the best results. ...

Soil Nutrients and Field Health: what you Need to Know
The soil on your field is like the brain to your body. It tells your crops everything they need to know to produce a healthy yield; how many organisms live there, what the pH balance is, whether or not something is performing well… For the brain, if something isn’t performing well, the body can react catastrophically. The same thing happens with soil. If you have too much ...

Monitoring greenhouse gases from biofuel crops
Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...
