Abstract

Evaluation of changeable agregat stability was done almost one year after application of biochar during rainy season 2010/2011 of three cyles maize planting in dryland of North Lombok. Three points of undisturbed soil samples in depth 0-20 cm were collected one month after maize harvest of previously addedbiochar land. Site of soil sample was treated by application of organic matter consisting of biochar coconut hust (BTK), biochar cow manure (BKS), one season application of manure (PKA), each season aplication of manure (PkB) and control (K : without soil amandement). The results showed that after one year application of biochar increased the limited value stability of soil agregat. The value was 61,37% and 61,18% for BTK and BTS, respectivel, while for treatment of PkA, PkB dan control gave value 58,44%, 66,62% and 57,11%. Increasing stability of soil agregat after application of organic soil amandement positively correlated with i the increase of soil organic and water soil retention. Therefore, experiment suggested that modification is needed for application biochar and manure in long period of maize cropping pattern in dryland of North Lombok

Abstract

Improved management of dryland agriculture could be one strategy to increase cassava production in order to meet national demand particularly for food and bioetanol industry. A field experiment was carried out to evaluate the influence of biomass modification addition (biochar, cattle manure, and corn-straw) on the growth and yield of cassava grown on sandy soils of northern Lombok. The treatments tested were: without addition of organic biomas as control (M0); the straw was put in the lowest part of rhyzoshere, biochar in the middle and subsequently followed by manure mixed with soil on top (M1); biochar, cattle manure, straw were mixed thoroughly within rhyzosphre (M2); biochar and cattle manure were only mixed with soil (M3); the manure was put down in the bottom part of rhyzoshere, straw in the middle and subsequently followed by biochar mixed with soil on top (M4). Results of the research showed that modification of biomass addition (biochar, manure and corn-straw) within soil increased significantly the growth and yiled as a results of better nutrient retention compared to soil without organic addition. The yield was increased by 32 and 33% at M1 and M4 respectivelly and reached closed to 40% at treatments of both M2 and M3 (27 t/ha)

Abstract

The aims of this study to were evaluate potential of biochar for improving several soil physical characteristics and yield of maize in a sandy loam soil of North Lombok during three cyles of sowing times (December 2010-October 2011). Five treatments, i.e. application of coconut sheld biochar (BTK), application of cow dung biochar (BKS), application of famyard manure only for one season (PKA), applications of farmyard manure each season (PKB) and control (K). Biochar application increased C-organic, and concentration of nutrient (N, P, K, Ca and Mg), absorption of N, P, K and seed yield. During three seasons, application of biochar led to higher C-organic content and more stabile compared with farmyard manure application. It indicated that biochar was potential for sequenstration of CO2, increased micro pores and soil water retention. Water holding capacity of biochar treatment was higher than PKA (application farmyard manure only for one season) and control. Maize plants showed positive response to biochar applications. Seed yield of maize for three cyles of seasons were 5,54 t/ha, 5,51 t/ha for BTK and BKS, repectively. Application of manure each season, application of farmyard manure at one season and control treatments yielded 5,62, 5,36 and 4,83 t/ha of maize seed, respectively
