One of the crucial elements for livestock and human nutrition is selenium and its deficiency or toxicity can harm human and livestock health. The present study is designed with the aim of studying the effect of different levels of selenium fertilizer (Selcote-Ultra) and cow manure on the uptake of selenium in tall fescue. For this purpose, a pot experiment with complete randomized block design ...

In laboratory studies performed in the United States and Hungary, the dump fly Hydrotaea aenescens (Wiedemann) was reared successfully in manure of 1- to 8-wk-old dairy calves, and in manure from adult lactating dairy cows. Survival in manure collected from 1-wk-old calves was poor (7.2%), better in manure collected from 2- and 3-wk-old calves (53.5%), and best in manure collected from 4- to 8-...

Biochar and compost applications are alternative in improving soil chemical properties, such as Ultisol utilizing the current abundance of biomass waste. has long available properties takes longer to decompose than compost. This study aims compare effect biochar for several months incubation on properties. research was conducted with pot from plastic cup placed a greenhouse using non-factorial ...

A spreadsheet‐based manure transport and land application decision tool, MANURE$HAUL, was developed to provide farmers, custom applicators, and others involved with manure management a manure cost and labor calculator for liquid manure systems using top‐loading tank spreaders and nurse tanks. The manure hauling capacity was a function of the machinery set selected, manure tank capacity, and hau...

Arenosols in the Brazilian Cerrado are increasingly being used for agricultural production, particularly maize. These sandy soils are characterized by low soil organic matter, low available nutrients, and poor water-holding capacity. For this reason, adding biochar as a soil amendment could lead to improved water and nutrient retention. A greenhouse experiment was carried out using twelve bioch...

in order to study the effect of different types and rates of animal manure and spent mushroom compost on controlling egyptian broomrape (orobanche aegyptiaca perss.) in tomato (mill. lycopersicon esculentum), two studies were conducted on randomized complete block design with three replications at research green house, college of agriculture, ferdowsi university of mashhad and nemooneh field of...

In recent years, the application of cow manure waste as an adsorbent heavy metals in water and soil has increased. The analysis most effective adsorbents from materials that can reduce metals, while being low-cost easy to produce, is important agricultural field. This study investigated manure, such compost, biochar humic acid, analyzed capability adsorption mechanisms Cr, Pb Cd. experiments we...

A common practice on Israeli dairy barns comprises daily cultivation of the manure. Cultivation is a mechanical process used to break up and till the manure bedding and it results in a drier and aerated bedding and cleaner cows, which consequently reduces the incidence of mastitis. Cultivation was associated with a shorter survival of Escherichia coli in cultivated manure as compared with noncu...
