Few publications go beyond the  theoretical models and examine the practical issues  involved. Given the level of soil degradation,  mainly through erosion and nutrient mining,  recapitalization of soil nutrient stocks is central  to continued crop production. Combined nutrient  sources play a crucial role in supporting crop  production especially in the smallholder faming  systems. This book therefore examines keys issues  related to use of cattle manure, i.e., its quality,  mineralization and immobilization effects, yield  gains; and proposes logic of how to combine both  high and low quality manures with mineral  fertilizers. The issues raised in this book are  important to researchers, extentionist, development  practitioners and students studying agriculture.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844301861\"\u003e\u003ch3\u003eCattle manure quality, combinations with mineral fertilizers and related yield gains\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844301861","offer_id":39470059585629,"sku":"9783844301861","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/82224575-3695-438a-ae62-60810a03d6f8.jpg?v=1773297064","url":"https:\/\/shop.autorenwelt.de\/products\/combined-organic-and-inorganic-nitrogen-sources-von-nhamo-nhamo","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
