Scientifically based recommendations concerning the choice of deep banding versus traditional broadcast application of phosphorus (P) and potassium (K) for corn and soybean production in conservation tillage systems have been hampered by insufficient research and inconsistent results. Even when the decision is made (e.g. by strip-tillage corn farmers) to go with deepbanding of P and K, numerous...

Strip-till has been used at a large scale in east central Kansas as an alternative to earlier planting dates under a no-till system. To determine the effects of planting corn (Zea mays) under previously established strip-tilled fertilized rows, experiments were conducted on an Osage silty clay loam soil in 2006 and 2008 and on a Woodson silt loam soil in 2009, 2010, and 2011 using three differe...

Nitrous oxide (NO), produced primarily in agricultural soils, is a potent greenhouse gas and is the dominant ozone-depleting substance. Efforts to reduce NO emissions are underway, but mitigation results have been inconsistent. The leguminous perennial kura clover ( M. Bieb.) (KC) can grow side-by-side with cash crops in rotational corn ( L.)-soybean ( L.) systems. With biological nitrogen fixa...

the erosion in dryland caused decrease in yield and soil quality, especially in slope land with conventional tillage. to investigate effect of tillage and planting methods in slope land on erosion and yield of dryland wheat, an experiment was conducted in 2007 at kermanshah province. the statistical design for this research was strip split plots in rcb (randomized complete blocks) with three re...

Weed competition is a significant problem in maize (Zea mays, L.) production in Sub-Saharan Africa. Better understanding of weed management and costs in maize intercropped with beans (Phaseolus vulgaris, L.) during transition to conservation agricultural systems is needed. Changes in weed population and maize growth were assessed for a period of three years at Bungoma where crops are grown twic...

Abstract Wheat ( Triticum aestivum L.) production in Texas depends heavily on conventional tillage (CT) and a long summer fallow period, which contributes to soil degradation. This study compared the impact of reducing intensity (CT, no‐tillage, strip‐tillage) combined with cropping CT–summer wheat establishment, grain production, herbage mass from 2016 2020 three ecoregions (Coastal Plains, So...

Row-crop agriculture is under pressure to reduce sediment and nutrient losses to surface water resources by practicing less tillage and more precise application and placement of nutrients. Field studies started in 1997 were conducted through 2002 on very low to low P-testing (3 to 5 ppm Bray P1) and medium to high-P testing (11 to 19 ppm Bray P1) sites of a Nicollet-Webster clay loam complex at...

Efforts have increased to measure nitrate losses from farmland under different management practices due to environmental and public concerns over levels of nitratenitrogen (NO3-N) in surface and ground waters. This study evaluated the effect of conventional tillage (CT) and strip tillage (ST) practices and three N application rates on NO3-N concentrations in soil water at a 76 cm depth under ir...

Tillage is the main force of soil redistribution in agricultural land use and has been seen as more critical than water erosion. This study aims to evaluate effect tillage with standard disk vineyards. A representative area grapevines was selected, 39 inter-rows were selected test slope forward speed. In each inter-row, a strip collected, mixed 2 kg coloured sand used tracer, then replaced stri...

Gaining a greater understanding of the plant microbiota and its interactions with its host plant heralds a new era of scientific discovery in agriculture. Different agricultural management practices influence soil microbial populations by changing a soil's physical, chemical and biological properties. However, the impact of these practices on the microbiota associated with economically importan...
