“…The SOC density tends to increase as the ratio of inorganic fertilizers to organic amendments decreases (Hao X.Y. et al, 2003;Rasool et al, 2007;Sainju et al, 2008;Pan et al, 2009;Bhattacharyya et al, 2010). The increase in SOC density values ranged from <0 to >8 Mg/(ha·a), with an average of 0.33 Mg/(ha·a) (Franzluebbers, 2005;West and Six, 2007;López-Bellido et al, 2010).…”

Aim:Methodology: Results:Integrated use of organic and inorganic fertilizers has better effects on crop growth and yield components of crop as well as soil health than alone. The main objective of the study was to find out the impact of integrated nutrient management on yield and soil health in maize-wheat cropping system. The maize crop was harvested when cob sheath turned brownish and grains became hard and grains were separated from cobs by hand shelling. When wheat crop matured and dry plants from net -1 plot area were harvested and threshing was done by using wheat thresher and expressed as t ha . The soil samples were collected from different plots of the experimental field and were analysed for physical (bulk density, hydraulic conductivity) and chemical (organic carbon, available N, P and K) properties. Infiltration rate was measured at the experimental field with the help of double ring infiltrometer.Addition of NPK fertilizer along with organic manure and biofertilizers improved yield and increased organic carbon content, available N, P, K and infiltration rate and hydraulic conductivity of the soil while reducing bulk density. Application of 50% recommended dose of fertilizer + 50% recommended dose of nitrogen produced significantly higher maize grain yield and significantly higher wheat grain yields were recorded with the application of 100% recommended dose of fertilizer over control. Lowest bulk density, highest hydraulic conductivity and infiltration rate were recorded with the application of 37.5% recommended dose of fertilizer + 37.5% recommended dose of nitrogen + biofertilizer to wheat. Application of 50% recommended dose of fertilizer + 50% recommended dose of nitrogen to maize and application of 37.5% recommended dose of fertilizer + 37.5% recommended dose of nitrogen + bio fertilizer to wheat resulted in increased available N by 10.2, 19.6% and 15.5, 26.2%, available P by 13.7, 20.4% and 17

“…Dampak keberadaan bahan organik ini adalah terjadinya peningkatan jumlah dan volume pori tanah sehingga terjadi perbaikan aerasi dan dinamika reaksi unsur hara dalam tanah. Rasool et al [13] dan Asalam et al [14] menambahkan bahwa porositas tanah yang baik dapat mengurangi kepadatan tanah dan retensi terhadap pergerakan hara, menstimulasi dan meningkatkan aktivitas tumbuh-kembang perakaran tanaman dan keberagaman aktivitas mikroorganisme tanah.…”

ABSTRAKBahan organik telah terbukti berperan efektif dalam memulihkan kesuburan tanah. Indikator kesuburan tanah ini antara lain terletak pada kandungan C-organik tanah, jumlah populasi mikroba tanah, kandungan hara tersedia dan hasil tanaman. Penelitian ini dilakukan dengan tujuan mengetahui pengaruh dosis aplikasi kompos jerami-Biochar yang berinteraksi dengan pupuk kimia NPK, terhadap kandungan Corganik tanah, jumlah populasi Bakteri Pelarut Fosfat (BPF), ketersediaan P dan hasil tanaman padi sawah. Sasaran penelitian ini adalah mendapatkan interaksi perlakuan yang mampu memperbaiki kesuburan tanah, meningkatkan ketersediaan hara sehingga mendorong produksi tanaman lebih optimal, dan pemakaian pupuk NPK yang efisien. Percobaan dilakukan pada bulan April sampai dengan Agustus 2014 di kebun percobaan SPLPP Fakultas Pertanian UNPAD, berlokasi di Ciparay Kabupaten Bandung Jawa Barat. Perlakuan yang diterapkan adalah dosis kompos jerami-Biochar dalam 5 taraf dosis (0; 1; 2; 3; 4 t ha -1 ) dan dosis pupuk NPK dalam 4 taraf dosis yang semakin menurun dari dosis rekomendasi (100%, 80%; 60%; 40%), dengan menerapkan disain percobaan RAK pola faktorial. Hasil percobaan menunjukkan dosis kompos jerami-Biochar 2 t ha -1 mampu menyebabkan perbedaan respons yang signifikan dan tercapainya hasil tertinggi pada parameter respons kandungan C-organik tanah, jumlah populasi BPF, ketersediaan P, dan berat kering gabah. Interaksi 2 t ha -1 kompos jerami-Biochar dengan pupuk NPK mampu menurunkan pemakaian pupuk hingga 40%, pada hasil berat kering gabah tertinggi.Kata kunci : BPF, biochar, fosfat, kompos jerami, padi ABSTRACTOrganic matter has been shown to play an effective role in restoring soil fertility. These soil fertility indicators include, among others, the soil C-organic content, the population of soil microbes, the nutrient availability and plant yield. This study conducted with the purpose of assessing the impact of rice straw compost-Biochar and NPK chemical fertilizer application on soil C-organic content, phosphate solubilizer bacteria (PSB) population, P availability and crop production. The objective of this research is to get treatment interaction which is able to improve soil fertility, increase soil nutrient availability to encourage more optimal crop production, and provide the efficient use of NPK fertilizer. The experiment conducted from April to August 2014 in SPLPP experimental station of Agriculture Faculty UNPAD, located in Ciparay-Bandung regency West Java. Treatment applied is rice straw compost -Biochar in 5 level of doses (0; 1; 2; 3; 4 t ha -1 ) and NPK fertilizer in 4 levels of doses decreasing from recommendation dose (100%, 80%; 60 %; 40%), by applying the Complete Randomized Block design in the factorial pattern. The experimental results showed that 2 ts ha -1 of rice straw compost-Biochar was able to induce significant different responses and the highest soil C-organic content, number of PSB population, P availability, and dry weight of grain. Interaction of 2 ts ha -1 rice straw compost -Biochar...
