Agronomic Approaches for Increasing Iron Availability to Food Crops
نویسندگان
چکیده
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 foliar application of external Fe using a wide array of organic and inorganic materials; and (iii) genetic and breeding practices aimed at enhancing the uptake and translocation efficiency of Fe in crops. Agronomic development during the last five decades, especially the introduction of synthetic chelates to agriculture, has opened doors for successful crop production on highly calcareous soils.

Biofortification of cereals with zinc and iron through fertilization strategy
Zinc (Zn) and iron (Fe) deficiencies are well-documented public health issue and an important soil constraint to crop production. Generally, there is a close geographical overlap between soil deficiency and human deficiency of Zn and Fe, indicating a high requirement for increasing concentrations of micronutrients in food crops. Breeding new plant genotypes for high grain concentrations of Fe a...
متن کاملBiofortification: Evidence and lessons learned linking agriculture and nutrition
Biofortification, the process of breeding nutrients into food crops, provides a comparatively cost-effective, sustainable, and long-term means of delivering more micronutrients. The biofortification strategy seeks to put the micronutrient-dense trait in those varieties that already have preferred agronomic and consumption traits, such as high yield and disease resistance. Marketed surpluses of ...
