    en.wikipedia.org/wiki/Nutrient_management

    Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...

    en.wikipedia.org/wiki/Living_mulch

    Living mulch planted to retard weed growth between corn rows. In agriculture, a living mulch is a cover crop interplanted or undersown with a main crop, and intended to serve the purposes of a mulch, such as weed suppression and regulation of soil temperature.

  4. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Nitrogen fertilizers are made from ammonia (NH 3) produced by the Haber–Bosch process. [28] In this energy-intensive process, natural gas (CH 4) usually supplies the hydrogen, and the nitrogen (N 2) is derived from the air. This ammonia is used as a feedstock for all other nitrogen fertilizers, such as anhydrous ammonium nitrate (NH 4 NO 3 ...

    en.wikipedia.org/wiki/Nitrogen_and_Non-Protein...

    When discussing the application of nitrogen in agriculture, it is essential to consider the sources of nitrogen used. Synthetic nitrogen fertilizers, such as ammonium nitrate and urea, are commonly applied to crops to replenish soil nitrogen levels and enhance crop productivity [3] These fertilizers provide readily available nitrogen for plant ...

    In many situations, however, a soil-, seed- or foliar application of a Mo fertilizer is far more cost-effective than the use of lime to increase Mo availability. Sodium molybdate is a typical source of Mo. Typical soil and foliar application rates are 50–200 g Mo ha −1; recommended rates for seed treatment range from 7–100 g Mo ha −1. [1]

  7. Seaweed fertiliser - Wikipedia

    en.wikipedia.org/wiki/Seaweed_fertiliser

    Foliar applications of seaweed fertilizer extract have been shown to improve the uptake of nitrogen, phosphorus, potassium, and sulfur in soybeans such as Glycine max. [59] Research has also demonstrated that brown algae seaweed extracts can improve tomato plant growth, overall crop yield, and resistance to environmental stressors. [ 60 ]
