Straw Incorporation Effects on Net Photosynthetic Carbon Assimilation and Maize Growth

open access: yesFrontiers in Agronomy, 2022
Returning straw into soil could increase soil organic carbon (SOC) and promote crop growth. However, little has been reported on the source of C for increased SOC (straw C or crop photosynthetic C). To investigate the assimilation of photosynthetic C and

NITROGEN FERTILIZERS

open access: yes, 2023
Nitrogenous fertilizers are organic and inorganic substances that contain nitrogen and are used as a source of nitrogen nutrition for plants, a source of nitrogen nutrition for plants. Nitrogen fertilizers were produced in the chemical industry in 1914–18 after the industrialization of the synthesis of ammonia from atmospheric nitrogen and hydrogen.

Demand for Nitrogenous Fertilizers and Fertilizer Price Policy in Pakistan [PDF]

open access: yesThe Pakistan Development Review, 1976
One of the major constraints to an increase in Pakistan's agricultural production is low fertilizer input. Despite spectacular growth of fertilizer con¬sumption during the '60s the rate of fertilizer application in Pakistan remains below the optimal rate [8, pp.77-90] and far below the rates in advanced countries [15, p. 24].
