Managing dryland requires intergrated knowledges on soil, water and plants relationship in order to achieve maximum yield. Using local and unused resource is important not only in aspect of reducing pollution but low price and also affordable for farmers. Thus, using amendment from in situ resources is suggested by many experts. This amendment used is assumed it could contribute improvement physical properties of soil and result better yields. This study aimed to studi more deeply on how much of soil amendment might improve physical properties of Cambisol under dryland environment and furthermore find out the crop response to soil amendments. The research was conducted during July to Oct. 2016 at Gampong Paud, Muara Tiga District, Pidie District, Aceh Province with the altitude ± 30 m asl and slope 0-3 %. A Randomized Completely Block Design (RCBD) with two factors replicated three times was used. First factor was soil amendment consisting of 4 levels ; no amendment (control), cow manure amount 10 ton ha -1, straw compost 10 ton ha-1, and cow manure 10 ton ha -1 + compost 10 ton ha-1. The second factor was 5 varieties of peanut: Tuban, Hypoma 2, Bima, Kelinci and Gajah. The parameters observed were soil bulk density, permeability, total soil porosity, aggregate stability index, soil water holding capacity at water potential -3 and -15 bar. Results of our studies showed soil amandement improves some soil physical properties, combination amendment with variety of peanuts resulted significant effects to soil physical properties, and combination treatments mostly influenced soil physical properties at soil depth of 0 -20 cm. Addition of 10 tons ha -1 cow manure or 10 ton ha -1 straw compost is enough to improve soil physical properties

Biochar is known as a huge carbon storage in the soil. In the soil, biochar absorbs CO2 from air and keep them for hundred years. In addition to preventing reduce emission and green house effects, Biochar also contributes to soil productivity such as physical dan chemical properties of the soil. How biochar amends soil physical properties combined with some tillage systems are imperative to find out. Study aimed to determine the influence of biochar and tillage systems on some soil physical properties. Treatment arranged in a factorial randomized block design with three replications. The treatment of biochar effect consisting of four levels; 0, 10, 15, and 20 t ha-1 Biochar. The tillage systems were three levels; no, minimum, and conventional tillage. The results showed that we found an interaction effect on the biochar application with tillage systems on dried bulk density, soil porosity, and soil permeability. No interaction was found on aggregate stability indexes and soil water holding capacity at water content at -0.3 and -15 bar of water potential (pF 2.54 and 4.2, accordingly). Biochar amounting 10 t ha-1 combined with minimum tillage gave significant benefits on soil productivity in terms of dried bulk density, porosity and soil permeability.

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.
