Rice husk biochar and compost application are expected to improve soil chemical properties such as pH, organic carbon, and available P in Ultisol, which in turn improves crop growth and P uptake by plants. The purpose of this research was to analyze the effect of the combination of rice husk biochar and compost on the soil chemical properties (pH, organic carbon, and available P), maize growth, and P uptake by maize in an Ultisol. The research used a Randomized Block Design with six treatments (P0: control; P1: 4 t biochar ha-1; P2: 30 t compost ha-1; P3: 4 t biochar ha-1 and 30 t compost ha-1; P4: 8 t biochar ha-1 and 30 t compost ha-1; P5: 4 t biochar ha-1 and 60 t compost ha-1) and four replications. The result showed that the combination of 8 t rice husk biochar ha-1 and 30 t compost ha-1 showed a significant effect on increasing pH, organic carbon, and available P in an Ultisol, increasing the height of maize crops at 4 and 6 WAP (weeks after planting). However, it had no effect on the number of leaves and showed an effect on the increase in P uptake of maize crop.

The Impact

Biochar improves soil quality physicochemical. Biochar is a soil amendment created through the burning of biomass, has a potential solution for wide-ranging environmental management problems. Biochar has been shown to have positive outcomes on soil function to sequester carbon to slow the effects of global climate change. The objective of this research was to study the impact of compost biochar in increasing rice yields in tropical swampland. The design used in this study was a randomized block design, including (1) biochom 1 (without harvest waste compost + without biochar rice husk), (2) Biochom 2 (harvest waste compost 5 t/ha), (3) biochom 3 (rice husk biochar 5 t/ha), (4) biochom 4 (a combination of harvest waste compost 2.5 t/ ha + rice husk biochar 2.5 t/ha). The results showed that application of biochom 4 (a combination of harvest waste compost 2.5 t/ha + rice husk biochar 2.5 t/ha) increased of rice yield reached 15.21% compared to biochom 2 treatment (compost harvest waste 5 t/ha) and reached 17.78% with biochom 3 treatment (rice husk biochar 5 t/ha), compost without biochar treatment.

Rice Husk Biochar

Bamboo chips, palm shells, and rice husks waste are environmental pollutants, but have the potential to be processed by pyrolysis to become biochar. Biochar is organic products rich in carbon, high in micro pores and very suitable for amending degraded (damaged) lands. Quality of biohar to be used as a soil amendment is highly dependent on is the raw material (feedstocks) to make biochar itself. The research objective was to find out the most suitable type of biochar to be used as a soil amendment for ex-mining land, so that the growth and production of plants can be optimum. The research has been carried out in the experimental station of the Syiah Kuala University Banda Aceh from August to December 2019 using soil from ex-excavated coal mines of PT. Mifa in West Aceh, Aceh Province. The plant parameters studied were morphological parameters of plant roots (length, weight, specific root length and ratio of roots to plant shoot), nutrient uptake of N, P, and K planted on ex-mine excavated soil. The study was designed using a non-factorial randomized block design consisting of two observation treatment factors, namely the type of biochar treatment (bamboo, palm shell, rice husk) and the dose of biochar (0, 10, 20 ton ha-1), and repeated 3 times. The observations that were observed included the components of root morphology and nutrient uptake of N, P and K plants. Biochar characteristics were analyzed using a Scanning Electron Microscope (SEM). Chemical-physical analyses of soil and plants were based on the procedure issued by the Soil Research Institute, Bogor. The effect among treatments was carried out by a variance analyses test (ANOVA) and if there was an effect, the honestly difference test (Tuckey-HSD) was continued at the level of 0.05. The results showed that the type of biochar had a significant effect on root morphology and nutrient uptake of N, P and K plants. Application biochar of rice husk with the amount of 20 tons ha-1 showed the best treatment for all the parameters studied, this is because nitrogen content in rice husk biochar contribute to growing corn crop. This study also found that bamboo biochar and palm shells gave a negative response when the amount of administration was increased to 20 tonnes ha-1 except for rice husk biochar.

The results showed that there was an increase of N, P and K uptake by rice with the application of 25% compost + 75% biochar. The treatment increased plant height, total tiller number and grain weight by 30 cm, 25.34 stems and 5.47 t ha-1, respectively higher than that in control.

ABSTRAK Bibit kelapa sawit yang baik salah satunya ditentukan oleh media tumbuh. Penggunaan kompos ataupun pupuk kandang sering berhasil memperbaiki produktivitas tanah dan mensuplai unsur hara ke tanaman. Namun, keuntungan pembenah tanah seperti ini bersifat jangka pendek, terutama di daerah tropis, karena dekomposisi bahan organik yang diberikan berlangsung cepat dan biasanya mengalami mineralisasi menjadi CO2. Karbon hitam (C), yang disebut sebagai biochar dapat mengatasi beberapa keterbatasan suplai bahan organik. Penelitian ini bertujuan untuk mendapatkan komposisi media tumbuh biochar yang sesuai untuk pertumbuhan bibit kelapa sawit. Penelitian menggunakan Rancangan Acak Kelompok dengan 10 perlakuan dan tiga ulangan. Perlakuan yang diuji adalah (1) Topsoil 100%, (2) Biochar sekam padi 100%, (3) Topsoil 50% + biochar sekam padi 50%, (4) Topsoil 50% + kompos 50%, (5) Topsoil 66,6% + biochar sekam padi 33,4%, (6) Topsoil 66,6% + kompos 33,4%, (7) Topsoil 33,3% + biochar sekam padi 33,3% + kompos 33,4%, (8) Topsoil 50% + biochar sekam padi 25% + kompos 25%, (9) Topsoil 40% + biochar sekam padi 40% + kompos 20%, (10) Topsoil 25%+ biochar sekam padi 50% + kompos 25%.

This study adopted a factorial randomized block design with three factors and three replications. The P1 treatment was recommended by the Swamp Land Agricultural Research Institute by adding chicken manure (5 ton ha−1) and rice husk biochar (5 ton ha−1) while the P2 treatment was recommended by the Vegetable Research Institute by adding chicken manure (10 ton ha−1). The raised beds heights were 20 cm (A) and 30 cm (B). Variance analyses were applied to each observation variable and followed by Duncan's Multiple Range Test at a 5% level. The P1A treatment was the best in improving the shallot production up to 10.88 tons and producing the lowest CO2 cumulative flux up to 0.158 ton ha-1 season-1.

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.
