Improving the Nutrient Efficiency of Tree Crops
Introduction Essential mineral nutrients applied to crops are a cost to growers and, poorly managed, contaminate air and/or water resources. Over the past 30+ years, fertilizer costs (USDA, 2006) and evidence of the negative impact of fertilizer nutrient contamination of air and water resources have increased significantly (Tilman et al., 2002). Therefore, an increase in nutrient efficiency, me...
متن کاملSurvey the Effect of Cover Crops in Reduced Sunflower Weed Biomass
In order to evaluate the effects of cover crops on reduced weed biomass in hybrid sunflower an experiment was carried in the research stations, Natural Resources Medicinal Plants (Samian_Ardabile) with 3 replicates in 1390-1391. The first factor was considered three type of cover crops, winter rye, spring barley, winter wheat with 2 control treatment, second factor was mulch management at two ...

متن کاملNutrient Use Efficiency in Plants
Invariably, many agricultural soils of the world are deficient in one or more of the essential nutrients needed to support healthy plants. Acidity, alkalinity, salinity, anthropogenic processes, nature of farming, and erosion can lead to soil degradation. Additions of fertilizers and/or amendments are essential for a proper nutrient supply and maximum yields. Estimates of overall efficiency of ...
متن کاملMaize productivity and nutrient use efficiency in Western Kenya as affected by soil type and crop management
Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...
