Deficiencies of Secondary Nutrients in Crop Plants—A Real Challenge to Improve Nitrogen Management

Organic Farming: Challenge of Timing Nitrogen Availability to Crop Nitrogen Requirements

being an environment friendly and more sustainable farming system. Ironically, scientists one-half century Groundwater has become increasingly degraded by NO3, and this ago devoted much research emphasis to providing farmdegradation has been partially attributed to the use of commercial inorganic N fertilizers. Conversion from conventional fertilizer maners information on the beneficial use of ...

Evaluation of Tillage, Nitrogen Fertilizer and Crop Residue Management on some Agronomic Traits of Soybean

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Absorption of Nutrients From Subsoil in Relation to Crop Yield

Nutrient deficiencies secondary to bariatric surgery.

PURPOSE OF REVIEW The number of adolescent and adult patients submitting to bariatric surgery is increasing rapidly around the world. This review describes the literature published in the last few years concerning nutritional deficiencies after bariatric surgery as well as their etiology, incidence, treatment and prevention. RECENT FINDINGS Although bariatric surgery was first introduced in t...

Secondary and Micro Nutrients

Calcium Absorbed form the soil as the cation, Ca. Most calcium uptake occurs near the root tip. Poorly translocated within the plant. Deficiencies of Ca first affect the growing points of plants, including root tips. Calcium is important for cell wall formation and the integrity of cell membranes. Sensitive crops to Ca deficiency and characteristic symptoms. Crop Symptoms Peanuts Old leaves hav...
