Abstract

Beef cattle feeding operations or feedlots generate large amounts of manure that negatively affect the environment. In order to reach an integrated farming system, setting a final destiny for these wastes not to damage the environment, the use of cattle manure in partial or total replacement of inorganic fertilizers has been evaluated. The study was done in sub-humid, sandy pampas region, on an Entic Hapludoll soil. The field experiment was performed using wheat. Four treatments were carried out as follows: a control treatment on the one hand and other three treatments on the other, containing a 116 kg N ha-1 isodose: Inorganic Fertilization (IF), Manure (M) and a mixture of Manure and Inorganic Fertilizers (M-IF) in equal parts. Results show M-IF treatment as the most efficient one, because it had the highest yield with the least negative effects over the environment.

Highlights

Beef cattle feeding operations or feedlots generate large volumes of manure which can negatively impact the environment [1,2]
The aim of this study is to evaluate the use of cattle manure in partial or total replacement of inorganic fertilizers in wheat production and assess its impact on soil properties
Treatment effects impacted on the following variables: grain yield, Dry Matter (DM), agronomic efficiency in N use (NAE) and P (PAE) (Table 2)

Summary

Introduction

Beef cattle feeding operations or feedlots generate large volumes of manure which can negatively impact the environment [1,2]. This residue has a high concentration of nutrients (N, P and K), minerals, trace elements, organic matter and pathogens, among others. Using manure in wheat production cropland is an alternative method to reduce feedlot environmental impact [5] and to achieve an integrated farming system [6]. Manure provides some of the essential elements for growth and development of crops due to its high nutrient concentration, which can significantly reduce fertilizing costs [4]. The increase in organic matter [7] (and moisture retention capacity) improves and maintains the soil properties
