Abstract

Peatlands have the potential to serve as productive agricultural land but possess low soil quality, necessitating innovative technologies to enhance soil quality and crop productivity. The improvement of peat soil quality can be achieved by utilizing ameliorants such as Red Mud and cattle manure. This study aims to investigate the role of Red Mud and cattle manure on the availability of macronutrients and the growth of hybrid corn plants in peat soil. The research was designed using a completely randomized design (CRD) with treatments of Red Mud and cattle manure. The first factor was Red Mud treatment at four dosage levels: without Red Mud (L0), 7 tons/ha (L1), 14 tons/ha (L2), and 21 tons/ha (L3). The second factor was cattle manure with four dosage levels: without cattle manure (P0), 50 tons/ha (P1), 100 tons/ha (P2), and 150 tons/ha (P3). The experiment was repeated three times, resulting in 48 experimental units. The results showed that the interaction between Red Mud and cattle manure significantly affected the parameters of exchangeable sodium availability and stem diameter. The single treatment of Red Mud had a significant effect on the parameters of pH, exchangeable potassium (K-dd), exchangeable sodium (Na-dd), cation exchange capacity (CEC), and plant height, with the best dosage being 21 tons/ha of Red Mud. The single treatment of cattle manure had a significant effect on the parameters of total nitrogen (N-total), available phosphorus (P-available), exchangeable potassium (K-dd), exchangeable sodium (Na-dd), and plant height, with the best dosage being 150 tons/ha of cattle manure. Keyword : amandement, peat soil, produktivity, quality

Abstract

Trichoderma spp. can act as a biofactor to accelerate decomposition, as a phosphate solvent and to control pests and diseases. This research aims to determine the effect of Trichoderma species and soil type on P uptake and growth of soybean plants (Glycine max.L). The research was carried out at the experimental field of the Faculty of Agriculture, Tanjungpura University. The experiment was carried out using the field experimental method with a Completely Randomized Design (CRD) consisting of 2 factors. Factor A is the type of soil and factor B is the type of Trichoderma. Factor A consists of 2 treatment levels and factor B consists of 3 treatment levels with 5 replications so that there are a total of 30 polybags. Factor A consists of 2 levels, namely peat soil and Ultisol and factor B consists of 3 levels, namely Trichoderma harzianum, Tricoderma koningii, and Trichoderma viride. The effect of treatment on observation parameters was analyzed using Analysis of Variance / Two way ANOVA. If there is a real effect of treatment on diameter, continue with the Tukey's Honestly Significant Difference Test (HSD-Tukey's). The results show that soil type and Trichoderma type have a significant effect on soil pH. Soil type treatment has a significant effect on plant height, plant dry weight, soil pH, soil organic carbon and soil available phosphorus. Treatment of Trichoderma types has a real influence on soil pH. The interaction between soil type and Trichoderma treatment had a significant effect on soil pH. Keywords: peat, P uptake, soybean,, Trichoderma, Ultisol. INTISARITrichoderma spp. dapat berperan sebagai biofaktor untuk percepatan dekomposisi, sebagai pelarut fosfat dan pengendalian hama penyakit.

Abstract

Red Yellow Podsolid (RYP) Soil has several properties that are less supportive for the growth and high yields of mustard greens (Brassica Juncea L). Soil properties such as nutrient content, organic matter and cation exchange capacity are very low. This research aims to examine the effect of adding N, P and K elements in granular organic fertilizer on the growth and yield of curly mustard greens in the RYP soil. The treatment  consisted of five treatments and was repeated five times so that there were 25 experimental units. The details of the treatment are as follows: Control (without applying fertilizer), Giving organic granule fertilizer, Giving organic granule fertilizer with a ratio of NPK (10 : 5 : 5), Giving organic granule fertilizer with a ratio of NPK (5 : 10 : 5), Giving organic fertilizer granules with NPK ratio (5 : 5 : 10). Providing N, P and K fertilizer at higher phosphorus doses was able to increase the growth of mustard plants by observing stem diameter by 38.84%, root fresh weight by 5.71% and plant fresh weight by 37.21%.Keywords: curly mustard greens, granulated organic fertilizer, RYP soil INTISARI            Tanah Podsolid Merah Kuning mempunyai beberapa sifat yang kurang mendukung untuk pertumbuhan dan hasil tanaman sawi (Brassica Juncea L) yang tinggi.

Abstract

Oil palm plantations managed by farmers in Kelompu Village, which is located on Ultisol land, are facing a decline in production due to low nutrient availability. The main limiting factor affecting soil productivity is the low availability of nutrients in the soil. One of the soil properties that greatly determines nutrient availability and plant productivity is the chemical characteristics of the soil. The research aims to study the chemical properties of soil on smallholder oil palm plantations in Kelompu Village. The research was conducted in Kelompu Village, Kembayan District, Sanggau Regency, with an area of around 20 hectares. There are four types of land based on farmer ownership and management. The survey and soil sampling method uses a grid system method. Soil samples were taken at a depth of 0-30 cm and 30-60 cm in a composite manner for analysis of soil chemical properties. Whole soil samples were also taken using a ring sampler at a depth of 0-30 cm. Soil analysis in the laboratory includes measuring soil pH, organic C content, total N, available P, K-dd, soil cation exchange capacity, soil base saturation and bulk density. Oil palm fields in Ultisol soil at all locations have similar soil chemical characteristics, with a tendency to have low nutrient levels. This was proven through analysis of soil samples which showed low levels of essential nutrient elements. In addition, limited management and land management practices, such as unbalanced fertilization, impact soil chemical properties and the availability of nutrients in the soil.Keywords: Ultisol Soil, Chemical Properties, Palm Oil INTISARIPerkebunan kelapa sawit yang dikelola oleh petani di Desa Kelompu, yang berada di tanah Ultisol, menghadapi penurunan produksi akibat rendahnya ketersediaan unsur hara. Faktor pembatas utama yang mempengaruhi produktivitas tanah adalah rendahnya ketersediaan hara di dalam tanah. Satu di antara sifat tanah yang sangat menentukan ketersediaan hara dan produktivitas tanaman adalah karakteristik kimia tanah. Penelitian bertujuan untuk mempelajari sifat kimia tanah pada lahan perkebunan kelapa sawit rakyat di Desa Kelompu. Penelitian dilakukan di Desa Kelompu, Kecamatan Kembayan, Kabupaten Sanggau, dengan luas areal sekitar 20 hektar. Terdapat empat jenis lahan berdasarkan kepemilikan dan pengelolaan petani. Metode survey dan pengambilan contoh tanah menggunakan metode sistem grid. Sampel tanah diambil pada kedalaman 0-30 cm dan 30-60 cm secara komposit untuk analisis sifat kimia tanah. Sampel tanah utuh juga diambil menggunakan ring sampler pada kedalaman 0-30 cm. Analisis tanah di laboratorium meliputi pengukuran pH tanah, kandungan C-organik, N-total, P-tersedia, K-dd, kapasitas tukar kation tanah, kejenuhan basa tanah dan bobot isi. Lahan kelapa sawit di tanah Ultisol pada semua lokasi memiliki karakteristik kimia tanah yang serupa, dengan kecenderungan memiliki kadar nutrisi yang rendah. Hal ini terbukti melalui analisis sampel tanah yang menunjukkan rendahnya kandungan unsur hara esensial. Selain itu, praktik manajemen dan pengelolaan lahan yang terbatas, seperti pemupukan yang tidak seimbang, berdampak pada sifat kimia tanah dan ketersediaan nutrisi dalam tanah. Kata kunci: Tanah Ultisol, Sifat Kimia, Kelapa Sawit
