Abstract
Animal manure (AM), such as swine, cattle, sheep, horse, as well as other organic waste materials from recycling agri-food or other processes may be used as nutrient source for horticultural annual and perennial crops, increasing nutrient cycling and reducing costs related to acquisition of industrial fertilizers. Additionally, over the years it is expected to modify chemical, physical, and biological soil attributes such as increasing the nutrient content in the soil, which can affect crop productivity, change the food composition, fruit and vegetable storage aptitudes, and impact on the environment. The present review addresses the effect of AM applications on the soil-plant interface, emphasizing the following aspects: (a) changes in chemical, physical and biological attributes in soils with a history of AM applications, (b) effect of application of AM on annual plant productivity and (c) AM as fertilizer: productivity and food composition of horticultural crops. Successive applications of AM in soils tend to increase the chemical and physical attributes, and, increased production of grain crops. Effect of AM fertilizations on quality and nutritional value of fruits is still uncertain; it depends on several factors, including: 1) characteristics of organic matter, 2) pedoclimatic conditions, 3) time of application and 4) plant species.
Highlights
The amount of waste to be applied can be established based on the percentage of dry matter, on nutrient concentration, and by the efficiency index, which is related to the total amount of nutrients contained in the waste that can be transformed from organic form to mineral form after its application in the soil (CQFS-RS/SC, 2016)
The only type of manure that does not necessarily result in an increase in total organic carbon content (TOC) content is the pig slurry (Cenciani et al, 2008; Andrade et al, 2016; Oliveira et al, 2014; Comin et al, 2013), which is associated with the low organic matter content in this type of waste
Bulk density reduces with the application of animal manures, both because the organic matter has a lower particle density than the mineral particles and its increase results in reduction of the soil particulate density as a whole, as because the increase of soil organic matter increases its degree of aggregation, increasing the volume of pores
Summary
The beginning of the 20th century was characterized by the intensive confinement of animals, be they cattle, pigs, birds, among others, aiming to increase productivity in small spaces. Increasing fertilizer costs and increasing concerns about soil and environmental quality deterioration have helped to increase the recycling of organic materials in agricultural areas (Comin et al, 2013, Singh and Ryan, 2015) In this sense, the present review addresses the effect of animal manure applications on the soilplant interface, emphasizing the following aspects: (a) changes in chemical attributes in soils with a history of animal manure applications, (b) changes in physical and biological parameters in soil areas with a history of animal manure applications, (c) effect of the application of animal manure on annual plant productivity and (d) animal manure as fertilizer: productivity and food composition of horticultural crops.
