Erosi tanah dapat menyebabkan terjadinya degradasi lahan dan lingkungan. Pengukuran erosi tanah sudah banyak dilakukan dengan tujuan untuk menentukan banyaknya tanah yang terangkut erosi sehingga dapat dilakukan pencegahan untuk meminimalisir terjadinya erosi. Penelitian ini bertujuan untuk mengetahui besarnya erosi pada lahan yang ditumbuhi tanaman aren (Arenga pinnata Merr) dengan tiga tingkatan umur tanaman di Kecamatan Lintau Buo Utara, Sumatra Barat. Penelitian dilakukan dari bulan November sampai Desember 2020 yang dimulai dengan melakukan survei pendahuluan di lapangan yaitu meninjau dan menentukan lokasi serta melakukan penentuan titik-titik pengamatan pada masing-masing penggunaan lahan. Pengukuran erosi tanah dilakukan dengan metode petak kecil pada lahan aren yang berbeda umurnya, serta dari lahan yang memiliki vegetasi rumput sebagai pembanding. Disamping tanah tererosi, beberapa sifat fisika tanah juga diamati, diantaranya tekstur, bahan organik, permeabilitas, bobot isi, dan porositas tanah. Hasil penelitian menunjukkan bahwa erosi pada lahan yang ditumbuhi aren lebih rendah dari lahan semak belukar. Besarnya tanah tererosi pada padang rumput mencapai 0,99 ton/ha, sedangkan pada lahan di bawah tanaman aren yaitu 0,91, 0,62 and 0,95 ton/ha pada tanaman berumur 6, 15, dan 25 tahun, secara berturut-turut. Hal ini didukung oleh sifat fisika tanah yang lebih baik di bawah lahan yang ditumbuhi aren, yang dicirikan oleh kandungan bahan organik yang tinggi (14,10-17,61%), bobot volume tanah yang rendah (0,44-0,63 g/cm3), total ruang pori tanah yang tinggi (76-83%), dan permeabilitas yang agak cepat (8,23-10,12 cm/jam). Tekstur tanah didominasi oleh partikel halus (debu dan liat) dengan kelas tekstur liat pada semak belukar dan liat berdebu pada lahan aren.

A research entitled the effect of various sources of organic matter on improvement of N,P,K Nutrient of Ultisol was conducted in Limau Manis Padang. The research was aimed to investigate the contribution of different source of organic matter to improve N,P,K content in soil. Field research was arranged in Randomized Block Design (RBD) consisting 5 treatments and 3 replications (blocks). Treatments are : A = no organic matter added, B = Tithonia, C = Paddy Straw, D = Imperata cylindrica, and E = Leucaena glauca. The dosage for each treatment was 20 ton/ha. The result showed that tithonia gave the best contribution in improving N,P,K content of Ultisol Limau Manis.Keywords :organic matter, N, P, K of Ultisols.

The endophytic bacteria are bacteria whose life cycle is partially or completely associated in the host plant tissue in various kinds of relationships (symbiosis) that it undergoes. The potential of endophytic bacteria as microbial resources is widely used as a biological control for plants, including as the producer of phytohormones and the agent of biocontrol and biofertilizer. This study aims to test selected endophyte bacterial isolates from chili as a biofertilizer to meet the nutrient requirements that are useful during the vegetative growth period of red chili in Ultisols. The study used a completely randomized design with 4 treatments and 3 replications, namely A = fertilizer N recommendation; B = Azospirillum sp AK+ Fertilizer N recommendation; C = Azospirillum sp BT+ Fertilizer N recommendation; D = Azospirillum sp DN+ fertilizer N recommendation. Azospirillum sp AK and Azospirillum sp DN isolates gave better vegetative growth than those of Azospirillum sp BT isolates with average dry weight, respectively, 19.49 g and 18.93 g and with a height of 29.67 cm and 29.60cm. The superiority of the 2 isolates was also shown in the observation of the number of leaves 30.39 and 22.50 and the number of branches 6.45 and 6.28 respectively for Azospirillum sp AK and Azospirillum sp DN isolates.Key words : Endophytic bacteria, red chili, Ultisols

A research about amelioration of psycho-chemical of Psamment by using organic mulch and techniques of conservation tillage on corn growth had been conducted in 2009. Field experiment was located in Korong Olo Bangau, Batang Anai, Padang Pariaman Regency. The general objective of the research was to improve fertility of Psamment and to find out the best tillage practice for corn growth based on soil and water conservation rules. The treatment consisted of two factors (3 x 5) which was designed in RBD. The first factor was tillage (No till, Minimum till, convensional till) and the second factor was mulch source (without mulch, Tithonia, Chromolaena, rice straw, and corn straw). Parameters analysed were either soil physical (moisture, BD, total pore, aggregation) or chemical (pH, N, P, and K) properties, as well as crop production. The result showed that both treatments were able to improve soil-physico-chemical properties of Psamment and corn yield. The value of BD decreased, soil organic mattere, total pore, and aggregation increased. Then, the soil pH as well as available P and K tended to increase. The highest yield (dry seeds) was found from combination between minimum tillage and tithonia mulch.Keywords: sifat fisiko-kimia, Psamment, mulksa, olah tanah konservasi, jagung.

Increased use of N fertilizer may substantially increase of nitrate nitrogen (NO3-N) leaching, which potentially pollutes groundwater. Leaching behaviour of nitrogen (N) was observed in the paddy field of forage rice cultivation. Two kinds of animal manure, cattle manure (CM) and poultry manure (PM) at 5 levels of N application (0, 70, 140, 210, 280 kg N ha-1) as the organic N sources, and without any chemical fertilizers. “Tachisuzuka” forage rice variety was conducted in the experimental plot. Porous ceramic cups were installed in triplicate of each treatment at 45 cm depth to collect the percolation water samples during the cultivation rice periods. The concentration of total N, NH4-N, NO2-N and NO3-N of water (surface and percolation) and soil sample solution were analysed using a Hach DR/2800 spectrophotometer. Result showed that NO3-N leaching was higher than NH4-N in the percolation water during the cultivation of forage rice periods. The highest NO3-N leaching was found in 280 kg N ha-1 (6.3 mg L-1), that it was indicated on the polluted levels. The highest of biomass production was in N280 (16.22 t ha-1) and nearly similar result in N140, N210 and N280. It was concluded that the best application of N-fertilizer in 140 kg N ha-1 because it greatly enhanced N-fertilizer efficiency, and decreased steadily of NO3-N concentration leaching in the environment of the groundwater.Keywords: Ammonium (NH4-N), Forage rice, N behavior, Nitrate (NO3-N), N leaching[How to Cite: Gusmini, K Nishimura, Adrinal, and T Itani. 2013.

Japan is the 3rd largest importer and consumer of coffee in the world. Considering have many demands of coffee, Japan is looking alternatives for improving to growing and the productivity of coffee. The research was aimed to assessment land suitability class for (arabica and robusta) coffee and land suitability evaluation of coffee. 3 soil samplings were collected from the study area. Matching method is used to evaluate the land suitability with parameter: temperature, elevation, rainfall, slope, pH, and nitrogen. The results showed that climate and physical condition of land area very suitable to grow robusta crops, and its level appropriateness is S1 (highly suitable). However, typhoon is problem in every year for growing coffee crops, but it can be handling by planting protecting crops.
