Abstract

Sriratmini et al, 2019. Utilization of Biochar to Increase Sub Optimal Land Productivity. pp. 502-509. Biochar obtained through the incomplete combustion and minimum oxygen, the material used can be agricultural wastes obtained from around us. Utilization of agricultural waste provides two functions, namely as a function of the environment and also the function of land fertility, especially suboptimal land. Utilization of suboptimal land as agricultural land is constrained by the physical, chemical and biological properties of the soil. This paper discusses some of the functions of biochar associated with increasing suboptimal land productivity both physically, chemically and biologically. From the results of some literature is known that the role of biochar will be greatly influenced from the combustion process, combustion temperature, source of raw materials used, the type of soil and and how the application. Biochar applications on suboptimal land can improve soil chemical properties, soil biology and soil physical properties. Improvement of soil properties will improve land productivity and crop productivity.

Abstract

Djafar et al, 2019. The Impact of Administering Liquid Biological Fertilizer on the Growth of the Palm Oil Seed (Elaeis quineensis Jacq.) in Main Nurseries Planted in Ultisol Land. pp. 193-197.The objective of this study was to see the impact of the use of liquid biological fertilizer on the growth of oil palm seedlings in the main nurseries planted in the Ultisol land. This study was conducted in Sukarami Vilaage, Alang-alang Lebar Subdistrict, Palembang City, from August 2011 to November 2011. The design of the study used was a randomized block design which was arranged factorially. The factors were the amount of fertilizer and the time to administer the liquid fertilizer. One factor consists of 4 subfactors of fertilizer dose (25%, 50%. 75%, and 100%); and the other one consists of 3 subfactors of fertilizer time (once in 5 days, once in 10 days, and once in 15 days). Each treatment was carried out with three replications. The variables observed in the plant growth were: plant height, number of leaves, stem diameter and total leaf area. The measurement was carried out every 3 weeks, until the seedlings were 3 months after planting. The study used polybags measuring 40 cm x 50 cm. The media of growth was in the from of top soil of Ultisol type, from former rubber plantation. Each polybag was filled with soil with a weight of 15 kg in dry air condition. Each polybag is labeled according to the treatment. The seeds used were from early 3-month- old nurseries. After the polybag was ready to be planted with the seedlings of 3 months old and it was placed in a open area in accordance with the treatment chart. Then it was treated and maintained. The results of the study showed that the fertilizer dosage and the time of fertilizer application and their interaction did not have an impact on the growth of the main seddlings.

Abstract

Riyanto et al, 2019. The Application of Biochar and Biofertilizer for Improving Rainfed Lowland and Rice Productivity on Gunungkidul Regency. pp. 206-215.Managing land resources and improving soil quality are currently urgent and very important for the sustainability of the next generations. Improvements in the quality of rainfed rice fields can be carried out, among others, by application of biofertilizers and biochar. Biofertilizer is a group of living organisms whose activities can improve soil fertility. Biochar is a solid material obtained from the carbonization process of a biomass of agricultural or plantation waste.  The objective of this research was to study the effect of biofertilizer and biochar on availability of N, P, K and C-organic and rice production. The assessment of the application of biological and biochar fertilizers was carried out in the rainfed rice fields of Wareng village, Wonosari district - Gunungkidul regency. The time of implementation was planting season II (February-June 2017) with the treatments: (A) Control (without biological fertilizer and biochar) +100% chemical recommendations fertilizer (Urea 175 kg / ha + NPK 235 kg / ha), (B) Application of Biofertilizer (Agrimeth) 400 gr / ha, without biochar + 100% chemical recommendations fertilizer (C) Application of Biofertilizer (Agrimeth, without biochar and 50% chemical recommendations fertilizer (D) Application biochar rice husk charcoal 2.0 tons /ha, without biological fertilizer and chemical fertilizer 100% recommendation, (E) Application of Biofertilizer (Agrimeth), and biochar 2 t / ha + 100% chemical recommendations fertilizer (F) Application of Biofertilizer (Agrimeth), and biochar 2 t/ha and 50% chemical recommendation fertilizer. Each treatment was repeated 4 times with the farmer as a replication. The experimental design used RCBD (Randomized Complete Block Design) with 4 times replications. The size of the plot followed the size of farmer ownership (On Farm Reserach). The research was shown that the application of Agrimeth biofertilizers and biochar of rice husk charcoal about 2 ton / ha gives a significant effect on the increase of  Milled Rice  production compared to without biofertilizer and biochar. The reduction of inorganic fertilizers by 50% Ponska has no significant effect with the application of 100% recommended  chemical fertilizers if added with the application of Agrimeth and biochar as much as 2 tons / ha. This indicates that the application of Agrimeth biofertilizer on rainfed lowland rice can increase NPK nutrient uptake while the application of rice husk biochar can increase the C-organic content and stimulate the biological activity of paddy soil and reduce the use of NPK inorganic fertilizers. The availability of NPK elements after application with rice husk biochar and Agrimeth biofertilizer showed that the total N content increased by 22.17%, available P and available K increased by 30.19% and 40.09% respectively compared to controls (treatment of local Farmers ) Likewise, the yield of Milled Rice (MRY) increased with the application of a of biochar and biofertilizer by 37.98%, whereas with a single application (only biochar or biofertilizers) only increased between 14.22-20.16% compared to treatment control.
