Abstract/ Executive Summary:

The experiment was carried out by anaerobic composting with layer droppings (T₁), layer droppings with straw (T₂), layer droppings with fodder residues (T₃) and layer droppings with saw dust (T₄) under soil surface to study the suitable method with layer droppings and their nutrient composition. The sample from composted materials was collected at 0, 10, 20 and 30 d for proximate analysis. In 30 d of composting dry matter and organic matter were gradually decreased in every method and which were also differed among the treatments (p<0.01). Crude protein (CP) gradually increased in every method and was higher in T₃ (19.43%) and then T₁ (18.93%), T₄ (15.99%) and T₂ (14.61%) (p<0.01) at 20 d of composting. The crude fiber content gradually decreased in every method and was higher in T₂ followed by T₄, T1 and T₃ (p<0.01) considerably with the composting period. Ash content was increased in all treatments with the advancing of composting period (p<0.01). The C/N ratio was higher in T₄ (22.4) followed by T2 (22.2), T₁ (22.0) and T3 (21.9) (p<0.01) considerably with the composting period. The PH value in all treatments decreased up to first ten days then gradually increased with the increase of composting period. The pH value was higher in T₁(8.54) followed by T₂ (8.15), T₃ (8.10) and T4 (8.00) (p<0.01) at 30 d of composting period. The proximate compositions of all treatments were in acceptable range up to the end of composting period. Therefore, the results suggest that composting layer droppings with fodder residues improve the nutritional value of compost at 20 days of composting time.

Location: BAU, Mymensingh

Start Date: 00-02-2012

End Date: 00-03-2012

Program Area: Crop-Soil-Water Management

Commodity: Bio fertilizer

Objectives:

To determine the effectiveness of different bulking materials in reducing time of composting and to assess its quality on the composting process.

Methodology:

The experiment was carried out in the Goat and Sheep farm, Department of Animal Science, Bangladesh Agricultural University, Mymensingh, during the period from February to March 2012. The experiment was laid out in a Complete Randomized Design (CRD) with 3 replicate in each treatment. A place of comparatively high land was selected to prepare 12 similar pits whose diameter were 75 cm and depth 45 cm. Polyethylene bagswere set at the bottom and side wall of the pits to prevent leaching and water contamination from compost. After collection, all bulking materials except the sawdust, were cut by chopping machine to mix with layer droppings properly. The treatment of the experiment was mentioned as: layer droppings only (T₁), layer droppings with straw (T₂), layer droppings with fodder residues (T₃₎ and layer droppings with sawdust (T₄ In each treatment, 20 kg layer droppings were mixed with the bulking materials to fix the moisture level at 50%. After proper mixing of the materials, sample was collected from each treatment for chemical analysis. Then mixing materials were mixed in previously prepared pits according to the treatment, covered with eight cm soil layer and kept for 30 d for successful composting. ).

Achievement/Findings:

The results suggest that composting layer droppings with fodder residues significantly improves the nutritional values of compost at 20 days of composting time and may be a feasible means of preserving and converting layer droppings, into a good organic fertilizer for plant. In addition, this approach may also solve the disposal problem of poultry droppings in large poultry industries by utilizing it as fertilizer
