Agronomic Approaches for Increasing Iron Availability to Food Crops
Iron availability in calcareous soils, and Fe uptake and translocation in plants are major factors limiting the agricultural use of land. The nutritional value of crops as Fe sources for humans is often reduced due to Fe-deficiency in plants. Agronomic approaches to overcome these shortcomings include: (i) methods aimed at increasing the availability of indigenous soil-Fe; (ii) soil and/or foli...
متن کاملAssessment Maize Hybrids Response to Biological and Chemical Nitrogen Fertilizers
This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
متن کاملCadmium availability from granulated and bulk-blended phosphate-potassium fertilizers.
Recent field experiments have shown that high chloride (Cl) in irrigation waters can increase soil cadmium (Cd) uptake by crops because of the formation of soluble ion-pair complexes of Cd with Cl in soil solution. The present study was aimed at testing a hypothesis that KCl in granulated PK fertilizers may enhance Cd uptake by crops from Cd-containing P fertilizers because of close contact bet...
متن کاملPhosphorus availability and microbial immobilization in a Nitisol with the application of mineral and organo-mineral fertilizers.
The aim of this study was to evaluate P availability, P and C contained in the microbial biomass, and enzymatic activity (acid phosphatases and β-glucosidases) in a Nitisol with the application of mineral and organo-mineral fertilizers. The experiment was performed in a protected environment with control over air temperature and soil moisture. The experimental design was organized in a "5 x 4" ...
متن کاملOrganic Fertilizers and Composts
Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...
