Effect of Bulking Materials on Composting of Layer Litter

Abstract

Abstract:The experiment was carried out to examine the possibilities of making compost by using layer litter with different bulking materials and to assess the nutritive value of compost. To fulfill the objectives five treatments were considered e.g., anaerobic composting with layer litter (T 1 ), layer litter with straw (T 2 ), layer litter with tree leaves (T 3 ), layer litter with crop residues (T 4 ) and layer litter with saw dust (T 5 ) under soil surface. The samples from composted materials were collected at 0, 10, 20 and 30 days for proximate analysis. At 0 day of layer litter composting DM content did not vary significantly (p>0.01) var ied in all treatments. . At 10 day of layer litter composting DM content was the highest in T 4 (50.0%) and CF content was the highest in T 2 (22.2%) . CP content remained similar varied in all treatments . At 20 day of layer litter composting DM content was highest in T 4 (51.5% ), CP content was the highest in T 4 (19.5%) , CF content was the highest in T 2 (18.0%), Ash content was the highest in T 4 (18.5%) . At 30 day of layer litter composting DM content was the highest in T 2 (51.1%) and CP content was the highest in T 4 (17.6%) . The pH value decreased upto first tendays then gradually increased with the composting period and highest value was obtained by T 1 (8.40) then followed by T 2 (8.20), T 3 (8.15), T 5 (8.10) and T 4 (8.00) (p<0.01) at 30 d of composting. The C/N ratios increased (p<0.01) in all treatments with the advancing of composting period and highest value was obtained in T 4 (27.9) followed by T 1 (26.7), T 5 (26.3), T 3 (26.2) and T 2 (25.3) considerably with the composting period. So, it may be concluded that proximate composition of all samples at 20 days in T 4 treatment was acceptable up to the end of composting period. However, composting layerlitter with crop residues (T 4 ) was more effective compare to other treatments at 20 days of composting in terms of Dry matter, CP content, C/N ration and pH.

Influence of amount of red worm (Eisenia foetida) on the organic matter degradation during vermicomposting of cattle manure

“…Some small scale industry can be developed in our country in rural areas that may help to create some employment opportunity. Compost can also provide a steady supply of nutrients to growing plants and increase the soil ability to retain essential minerals (Stevenson, 1994;Alam et al, 2013;.…”

Socio economic status of beef fattened farmers of Kauniaupazila at Rangpur district of Bangladesh

“…Manure should be decomposed through composting, vermicomposting or anaerobic digestion before applied to the soil (Al Amin et al, 2020;Rahman et al, 2020aRahman et al, , 2020bRana et al, 2020;Roy et al, 2013;Sarker et al, 2021). Manure can be converted into valuable resources through proper treatment; otherwise it may be the cause of environmental pollution (Ahsan et al, 2013;Alam et al, 2013;Lee et al, 2009;Islam et al, 2010;Rahman et al, 2013;Sarker et al, 2009;Won et al, 2016).…”

Comparative study of growth performance of Deshi, Fayoumi, RIR and Sonalichicken reared under farm and semi scavenging condition

“…The old litter material was changed using new rice husk to prevent dampness. Poultry litter is also a good source of compost preparation that rich in macro and micro nutrients for plant growth (Alam et al, 2013). Vaccination, deworming and debeaking programmes of the experimental birds were shown in Table 3.…”
