A methodology for estimating the ammonia emission from crop residues at a national scale

open access: yesAtmospheric Environment: X, 2019
Crops and crop residues contribute to pollution of the environment by ammonia (NH3) volatilization. This study focusses on the volatilization from crop residues, defined as residues after a management action or frost i.e.

Assessment of Rice Residues as Potential Energy Source in Pakistan

open access: yesSukkur IBA Journal of Emerging Technologies, 2022
Pakistan produces enormous quantity of biomass wastes for example rice straw (RS) and rice husk (RH), wheat straw, and other biomass wastes that are being burned in the field after crop harvest to prepare the land for next crop.

To burn or retain crop residues on croplands? An integrated analysis of crop residue management in China [PDF]

open access: yesScience of The Total Environment, 2019
Crop residue burning influences human health and global climate change. In China-the world's largest crop residue producer-farmers burn almost one quarter of their crop residues in the field after harvest, despite the government providing financial incentives such as subsidies to retain crop residues.

Review of Alternative Management Options of Vegetable Crop Residues to Reduce Nitrate Leaching in Intensive Vegetable Rotations

open access: yesAgronomy, 2014
Vegetable crop residues take a particular position relative to arable crops due to often large amounts of biomass with a N content up to 200 kg N ha−1 left behind on the field.

Comparison of mineralisation and humification of postharvest residues of cereals in conventional and organic cropping practices

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2006
Yearly inputs and transformations of above – and underground plant residues of winter wheat and spring barley were followed in „intensive“ (I, mineral fertilizers only) and „organic“ (0, most of nutrients applied as animal manure) crop sequences.

A Review of Potassium-Rich Crop Residues Used as Organic Matter Amendments in Tree Crop Agroecosystems

open access: yes, 2021
Ecosystem-based approaches to nutrient management are needed to satisfy crop nutrient requirements while minimizing environmental impacts of fertilizer use. Applying crop residues as soil amendments can provide essential crop nutrient inputs from organic

Production of indigenous mushrooms spawn using crop residues as substrates

open access: yes, 2022
Indigenous oyster mushrooms occur naturally when conditions are favourable. Achieving good quality spawn is a major challenge to small-scale farmers in Kenya, who strive to domesticate indigenous mushrooms.
