Rice Husk Biochar

The importance to return organic matter to the soil has been widely recognized, especially to agricultural lands  that are low in organic matter and nutrients contents that will decrease the productivity of food crops. This study aimed to study the effect of  biochar (rice husk and corn cob biochar) and straw compost on soil chemical properties and yield of soybean (Glycine max (L.) Merr. The experiments were done in the laboratory and the field experiment at February–July 2015. The first study was laboratory test using a randomized block design with three replicates. Soil samples were ground and sieved to obtain the less than 4 mm fraction for the incubation experiment. A five kg  soil was mixtured with amandement treatments (A: control; B: Rice husk biochar 10 Mg ha-1 ; C: corn cob 10 Mg ha-1; D: straw compost 10 Mg ha-1; and E. Rice husk biochar 10 Mg ha-1 +  straw compost 10 Mg ha-1 ; F. corn cob biochar 10 Mg ha-1 +  straw compost 10 Mg ha-1) were filled into plastic pots. The treatments were incubated for 1 and 2 months. Soil samples measured were pH, Organic-C, Total-N, P2O5 (Bray-1), K2O (Morgan), Na, Ca, Mg, S, and CEC. The field experiment was conducted at Sukaraja Nuban Village, Batanghari Nuban sub district, East Lampung Regency. The treatments (similar too laboratory experiment) were arranged in a randomized block design with four replicates. Plot size was 10 m × 20 m, and soybean as crop indicators. The parameters observed were plant heigh, number of branches , number of pods per plant , number of seeds per plant, grain weight, and stover. The results of laboratory experiment showed that application of  biochar and compost improve soil fertility due to the increase in soil pH and nutrient availability for plant especially P2O5 and K2O available.  The treatment of  a rice husk biochar and compost mixture was better than single application to improve soil fertility and soybean yield. Apllication mixture husk biochar 10 Mg ha-1and straw compost 10 Mg ha-1 increased grain weight about 41% compost to control.Keywords: Biochar, compost, crop waste, soil chemical properties [How to Cite: Junita B, Dermiyati and H Sudarsono. 2016.

<p>An improvement in soil chemical properties and crop development with silicate application has been confirmed in several plant species. The effects of silicate application on soil chemical properties and wheat growth were investigated in the present study. The experiment was carried out in 8-L plastic pots in a greenhouse. Treatments were arranged in a randomized block design in a 3 × 5 factorial: three soils [Rhodic Acrudox (Ox1), Rhodic Hapludox (Ox2) and Arenic Hapludult (Ult)] and five silicate rates (0, 1, 2, 4 and 6 Mg ha–1 of calcium/magnesium silicate), with four replications. The plant length, number of spikes per pot, shoot dry matter and grain yield, were measured after 115 days of wheat (<em>Triticum aestivum </em>L.) growth. Changes in the soil chemical properties (pH, H+ + Al3+, Al3+, P, K, Ca, Mg, Si, Cu, Zn, Fe and Mn) were analyzed after wheat harvest. Application of calcium/magnesium silicate reduces the potential acidity (H+ + Al3+) and Al3+ phytotoxic; and increases the soil pH, available Ca, Mg and Si, cation exchange capacity (CEC) and soil base saturation. Silicate application did not affect the available P, exchangeable K and availability of micronutrients (Cu, Zn, Fe and Mn) in the three soils. The application of calcium/magnesium silicate in an acid clayey Rhodic Hapludox improves the development and yield of wheat; however, the silicate application in soil with pH higher to 5.3 and high Si availability does not affect the agronomic characteristics and grain yield of wheat.</p><p><strong> </strong></p>

This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.

Fertile agricultural land encourages people to carry out agricultural cultivation activities. But in general, it has decreased soil fertility because its managed intensively without recycling of organic matter and has an impact on decreasing soil fertility chemically such as soil organic carbon and pH then leads to low productivity. Soybean is an agricultural product that necessary to develop because the demand for soybean consumption in East Java Province has always increased. However, Indonesia has not been able to fulfil this demand. One of the technology innovations that can be applied to improve soil fertility that has low organic matter and to increasing soybean production by providing input of quality organic fertilizer in the form of compost (Tithonia and Cow Dung). So this research is important to determine the effect of application cow dung compost and tithonia on soil chemical properties, the growth of soybean crops, and the correlations between soil chemical properties and soybean growth. This study used a randomized block design with 6 treatments and 3 replications. The result showed that the application of tithonia and cow dung compost shows a significant effect on soil chemical properties, plant height, and the number of leaves, but didn’t show a significant effect on the number of branches in every observation. Based on the correlation analysis, the results show a positive correlation between soil chemical properties and soybean growth.
