BED TEMPERATURE IN COMPOST BARNS TURNED WITH ROTARY HOE AND OFFSET DISC HARROW REA
Mota,Vania C.; Andrade,Ednilton T. de; Leite,Daniel F..
ABSTRACT The success of confinement for dairy cattle in the compost barn model depends mainly on the management of the bed and consists of its turning. This paper characterises the spatial variability of the bed temperature in the compost barn confinement model, as well as verifying whether there was an effect on efficiency from turning the bed with different agricultural implements. The experiment was conducted during the summer and winter of 2016, with 8 days of collection in each period. Data were analysed with descriptive statistics methods and geostatistical modelling with semivariograms and kriging maps. The results of the t-test at a5% significance level indicated that, after turning the bed with the plough or rotary hoe, the temperature values were...

Utilization of bedded cattle confinement for organic manure of maize crop AGRIAMBI
Mota,Vania C.; Andrade,Ednilton T.; Pinto,Sandra M.; Abreu,Luiz R. de; Leite,Daniel F..
ABSTRACT The use of organic wastes from housing systems in a compost bedded pack barn model could supply much of the fertiliser demand in the farm. Moreover, with the increase in food consumption from sustainable livestock, the use of compost generated in the farm itself becomes economically viable. This study aimed to evaluate the effect of organic manure from bedded cattle confinement applied at different moments on maize crop. The experiment was carried out in a randomized blocks with five treatments and five repetitions. The data were submitted to analysis of variance and the means were compared by Scott-Knott test at p ≤ 0.05. The treatments with addition of fresh compost and mature compost with nitrogen cover had higher production of maize shoot dry...
