Organic Farm

With the continuing 20% growth rate in the organic industry, organic vegetable crop production has increased to 98,525 acres in the United States. The requirement for certified organic vegetable producers to implement a soil-building plan has led to the development of soil fertility systems based on combinations of organic fertilizers and cover crops. To determine optimal soil fertility combinations, conventional and organic bell pepper (Capsicum annuum) production was evaluated from 2001 to 2003 in Iowa, comparing combinations of two synthetic fertilizers and three compost-based organic fertilizers, and a cover crop treatment of hairy vetch (Vicia villosa) and rye (Secale cereale) in a strip-tilled or fully incorporated cover crop system. Organic pepper growth and yields equaled or surpassed conventional production when nitrogen (N) was provided at 56 or 112 kg·ha−1 from compost-based organic fertilizer. Soil analysis revealed higher N in plots where cover crops were tilled compared with strip-tilled plots, leading to recommendations for sidedressing N in strip-tilled organic pepper production. Increased incidence of disease was also detected in strip-tilled plots. Postharvest weight loss after 6 weeks in storage was similar in organic and conventional peppers. The addition of calcium and sulfur products in conventional or organic fertilizer regimes did not increase pepper production or postharvest storage potential. Despite application challenges, cover crops will remain as critical components of the organic farm plan for their soil-building benefits, but supplementation with approved N sources may be required for optimal pepper production. Organic growers should conduct their own tests of organic-compliant soil amendments to determine cost effectiveness and value for their site before large-scale application.

Исследования проводились на дерновоподзолистой среднесуглинистой почве нормального увлажнения. В опыте изучалось влияние органических и минеральных удобрений в разной дозе на видовой состав сорных растений в посевах и урожайность зелёной массы кукурузы. Применение в посевах кукурузы органоминеральных удобрений с полной и сниженной дозой привело к уменьшению доли участия многолетних видов на 11,1 и 11,5 соответственно, в сравнении с контролем. На данных фонах наблюдалось снижение доли участия пырея ползучего на 5,26,7, осота полевого на 2,83,5, бодяка полевого на 1,53,5, повышение доли участия чистеца болотного на 1,6. Внесение органических удобрений (сидератов, укосов многолетних трав) способствовало повышению доли многолетников на 13,3 в сравнении с контролем. С использованием органической системы земледелия на посевах кукурузы увеличивается доля участия хвоща полевого на 5,6, чистеца болотного на 4,2, осота полевого на 3,7, пырея ползучего на 3,2 снижается доля участия бодяка полевого на 3,6. Наибольшее число видов малолетних сорных растений (11 видов) отмечалось при внесении органоминеральных удобрений с полной дозой. Органическая система земледелия способствовала увеличению доли участия звездчатки средней, дымянки аптечной, яснотки пурпуровой, незабудки полевой, пикульника красивого и снижению доли мари белой, горцев. Урожайность зелёной массы кукурузы повышалась при внесении органоминеральных удобрений в полной дозе на 419 ц/га в сравнении с контролем.Researches were carried out on soddy podzolic medium loamy soil of normal moisture. The trial studied the effect of organic and mineral fertilizers in different doses on the species composition of weedage in sowings and the yield of green mass of corn. The use of organic fertilizer with full and reduced dose in corn sowings led to a decrease in the share of participation of perennial species by 11.1 and 11.5 respectively in comparison with the control. On these backgrounds there was a decrease in the share of participation of couch grass by 5.26.7, field milk thistle by 2.83.5, cursed thistle by 1.53.5, and the increase in the share of clowns woundwort by 1.6. The application of organic fertilizers (green manure, perennial grass cuttings) contributed to an increase in the share of perennials by 13.3 compared with the control. With the use of organic farming on corn sowings the share of participation of bottle brush increased by 5.6, clowns woundwort by 4.2, field milk thistle by 3.7, couch grass by 3.2 the share of participation of the cursed thistle decreases by 3.6. The largest number of species of very yuong weed plants (11 species) was observed when organic fertilizers were applied with a full dose. The organic farming system contributed to an increase in the share of participation of chickweed satin flower, drug fumitory, rabbitmeat, field scorpion grass, bee nettle and a decrease in the proportion of Chenopodium album and pepper plants. The yield of green mass of corn increased with the introduction of organic fertilizers in the full dose of 419 centner/ha in comparison with the control.

Microbiological Properties

Millions of organic fertilizers are produced annually all over the world. Substantial quantities of these were crop residues and the remaining being animal waste based. Meanwhile maintaining and improving soil fertility in the tropic is essential for increasing food production for rapidly expanding the population. This project work, therefore, investigated the variation in soil chemical and microbiological properties as a result of yearly amendment with compost. The experimental site was the Organic Agricultural Farm located within the Federal University of Agriculture, Abeokuta. Soil samples were collected between 0 – 15 cm depth using soil auger and the samples were analyzed for the following soil parameters; total viable counts, total fungal counts, microbial biomass carbon, microbial biomass nitrogen, percentage organic carbon, microarthropod counts and earthworm counts. The experiment was a split-plot design using 2 varieties of tomato x 3 levels of compost and two durations of application. The variations include one improved variety (UCB 8) and a local variety (Beske), rate of compost – (0, 10, and 20) kg/ha and years of application (one and two years). Results generally showed that: duration has a significant effect on viable counts, microarthropod counts, microbial biomass P, microbial biomass C and percentage organic carbon but has no significant effect on fungal counts, microbial biomass nitrogen, and earthworm counts. The results indicate that application of compost manure is the preferred option to enhance SOM accumulation, improve soil fertility and quality, and increase tomato yield.

ABSTRACTDegradation of soil fertility due to inaccurate application of fertilizer become one of the factors causing the stagnant rice productivity improvement in Indonesia. Straw incorporation, organic fertilizers and biofertilizers applications potentially reduces a rates of inorganic fertilizers and improves soil fertility. The aim of this study was to evaluate growth and yield of 3 lowland rice varieties (high yielding variety, new plant type, and local variety) in response to reduce NPK rates with straw incorporation, organic fertilizer, and biofertilizer in 7th planting season. The research was conducted at rice field in Karawang, West Java, from April-August 2013. The research was arranged in split plot randomized block design with 3 replications. The main plot was fertilizer application consisted of 10 treatments (combination of organic and inorganic fertilizers), while the sub plot was rice varieties (Ciherang, IPB 3S, and Mentik Wangi). The application of inorganic fertilizer, 400 kg NPK 30-6-8 ha-1, was control treatment. Plot size was 6.5 m x 10 m, with a double row spacing (25 cm x 15 cm x 50 cm). The result showed that growth of the three varieties was not significantly different so as the yield at 50% reduced NPK rate with incorporation of straw, organic fertilizer and biofertilizer. Adding of solid and liquid organic fertilizer, and biofertilizers on treatment of straw incorporation + 50% NPK rate was unnecessary due to insignificant yield increase.Keywords: Ciherang, fertilizer, IPB 3S, local variety, Mentik Wangi, new plant type

Low soil fertility, pests and diseases are major problems of growth and establishment of cacao seedlings on the field. Cocoa production increases by new plantings and rehabilitation of moribund farms, but a build-up of plant-parasitic nematodes (PPN) causing dieback and declining soil fertility has discouraged many farmers, leading to a reduction in crop productivity. In this study, the potentials of some organic wastes as fertilizers and their effects on establishment of cacao seedlings in PPN infected soils was investigated at Ibadan and Owena of Southwestern Nigeria. Goat dung (GD), organic fertilizer (OF), organo-mineral fertilizers (OMF) and NPK 15:15:15 were applied at 200, 400 and 600 kg ha-1, respectively, to cacao seedlings one month after transplanting, while unfertilized served as control. Results from the experiments showed a significant increase in percentage survival of cacao seedlings under organic fertilizers at Ibadan and Owena compared to NPK and control even at the lowest rate of 200 kg ha-1 3 years after transplanting. The incorporation of GD, OF and OMF significantly reduced the population densities of PPN compared to control. Therefore, GD, OF and OMF at 200 kg ha-1 are recommended for soil application to enhance the field establishment of cacao seedlings in the soil infected with PPN.

Service Activity

Counseling of Soil Fertility, Organic Fertilizers, Pests and Plant Diseases for Baranuri Farmers Group. The Baranuri Farmers Group (KT. Baranuri) is one of the providers of vegetables for the people of Ende City. The results of interviews with farmers obtained several problems, namely, there is no data on soil fertility and lack of understanding of soil fertility, organic fertilizers, pests and plant diseases. The solution given is to analyze soil pH and organic-C to be used as a reference for soil fertility conditions as well as counseling about soil fertility, organic fertilizers, pests and plant diseases. This service activity aims to provide information on soil fertility, increase farmers' knowledge regarding soil fertility, organic fertilizers and plant pests and diseases. The counseling method used is a group approach. Purposive soil sampling, samples were taken diagonally. The organic-C content was analyzed in the laboratory by Walkley and Black method, while soil pH was measured directly on the field using 4 in 1 Soil Survey Instrument and then matching with the criteria of assessment of soil analysis results by the Indonesian Soil Research Institute. The results obtained were the soil pH was 4-5 (very acidic-acidic) and soil organic C was 2.03-2.37% (moderate). The extension activities were succeeded in increasing public knowledge from 46.7% to 86.7% (an increase of 85.7%). The recommendation from this activity is to create a demonstration field to apply an organic fertilizer that can be observed directly by farmer groups.
