Application of Sheep Urine Fermentation and Biochar Coconut for Growth Vegetables Plant

The Covid-19 pandemic to date has had an impact on all sectors of life in society, which is the provision of food sources by society. Various efforts have been made to the fulfillment of food needs in the community can fulfill as they should so that food security can be realized during this pandemic. This research was conducted so that the community can fulfill their needs, especially food needs by utilizing waste, especially solid, and liquid waste and increasing the productivity of food crops to increase the fulfillment of community needs. This research was conducted applied soil ameliorant coconut biochar at coastal soil Samas beach. After that application sheep urine fermentation for add nutrient in the soil. The stages of carrying out this research include: taking soil samples, preparing materials for making biochar and urine fermented for fertilizer, nursery pakcoy, preparing planting media, soil ameliorant coconut shell biochar, transferring pakcoy seeds, maintaining and administering urine fertilizer treatment to planting media, and plant vegetative observations. The result application was added material both biochar and sheep urine fermented. It was mixed media can repaired root area in the soil and increase avaibility of nutrient for supporting growth of stem height, account of leaves, length, width, and color of the leaf with the application of coconut shell biochar dosage 15 tons per hectare mixed treatment sheep urine 100 ml per liter of water was best treatnment. It can good growth pakcoy plants. and Its benefit from a relatively short period, and It can reduce the use of chemical fertilizers that It can cause environmental degradation

Sustainable Management of Peanut Shell through Biochar and Its Application as Soil Ameliorant

The current research encompasses utilization of peanut shells (PS) as feedstock for pyrolysis carried out at various temperatures (250, 400, and 550 °C) for deriving biochar, namely PS-BC250, PS-BC400, and PS-BC550. After analyzing the biochar types physicochemically, it was applied as a soil ameliorant for the growth of cucumber. The results showed that in prepared biochar type, bulk density, volatile contents, hydrogen, oxygen, and nitrogen content decreased, whereas pH, electrical conductivity, ash content, fixed carbon content, and surface area increased with the increasing temperature. Scanning electron microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) presented high porosity, re-orientation of vessels, and a greater number of aromatic compounds, respectively, for PS-BC prepared at 550 °C. On applying PS-BC250, PS-BC400, and PS-BC550 as amendments in potted soil at 2, 4, and 6% (w/w), it improved soil quality (viz pH, ECe, BD, and soil water holding capacity) and increased the yield of cucumber. Because of improved soil properties and crop yield, PS-BC550 at the rate of 4% (w/w) demonstrated a great potential for agricultural application while provisioning dual circular economic indicators in the form of diverting PS waste to an effective alternative of chemical fertilizer having intensive carbon footprints in cucumber production.

Effect of mycosilvi and soil ameliorant to change aluminium concentration by Albizia chinensis in silica sand post mining soil medium

This study aimed to analyze the concentration change of Aluminum in the soil with addition of MycoSilvi and soil ameliorant in silica sand post mining soil media. There are three types of MycoSilvi, single or combination, added with soil ameliorant which tested on Albizia chinensis (Osbeck) Merrill. The experimental design used was a factorial design with two factors, MycoSilvi (M) consisting of four levels (M0 = without MycoSilvi; M1 = MycoSilvi type 1; M2 = MycoSilvi type 2; and M3 = MycoSilvi type 3) and soil Ameliorant (LC) consisting of four levels (L0C0 = without soil ameliorant; L1C0 = lime; L0C1 = compost; L1C1 = lime and compost). Data analysis used analysis of variance (ANOVA). The results showed that the combination of MycoSilvi and soil ameliorant decreased aluminum concentration from 7.70 to 0.10 cmol(+)/kg and increased pH from 3.20 to 5.67 were positively correlated with total biomass. Significant changes were shown in MycoSilvi type 3 with the addition of lime and compost (M3L1C1). Application of MycoSilvi type 3 (M3L0C0) gave equivalent response with application of lime (M0L1C0) to increased dry biomass, so that lime can be replaced with MycoSilvi type 3 (M3L0C0) to promote plant growth, especially biomass of plant.

Utilization of bio-organo mineral as a soil ameliorant for hard crops

The research objective was to make a formula for economical complex soil conditioner of bio-organo mineral for tea, coffee and cacao plantations. The soil conditioner (SC) formula for such plantations was made by mixing the urea, phosphate, leucite and kieserite with the ratio of 25:7:12:3. The experiments at Block B5 showed the amount of harvested dormant leaves was 3.37 kg/100 m2 while the control yielded 2.29 kg/100 m2. There is a difference around 1.08 kg/100 m2 or 47%. The amount of Peko shoots was 19.82 g/100 m2 when using the soil conditioner while the control had 14.89 g/100 m2 performing the difference 33% while at Block A10, the amount of harvested dormant shoot was 3.53 kg/100 m2. There is a difference around 3.29 kg/100m2 or 7%. The amount of Peko shoot was 18.25 g/100 m2 while the control acquiesced 15,05 g/100m2 – the difference of both was 21%. The Robusta grew from 25.4 cm to 28.5 cm when using the BIOM-SC. but the plant height is only from 24.4 cm to 26.8 when using NPK fertilizer.

Mycorrhizae and a soil ameliorant on improving the characteristics of sandy soil

<p>Agricultural constraints on sandy soil are poor chemical characteristics and low biological activity resulting in the soil becoming less productive to be planted. One of the efforts to improve the quality of sandy soil are application of mycorrhizae and a soil ameliorant. The purpose of this study was to determine the effect of mycorrhizae and a soil ameliorant on soil chemical characteristics and soil biological activity. The experiment was arranged using a Complete Randomized Design that had two factors. The first factor (1) was mycorrhizae dose, without mycorrhizae (M0) and six spores of mycorrhizae/plant (M1), and the second factor (2) was types of soil ameliorant, without ameliorant (S0), cow dung (S1), rock phosphate (S2), biochar (S3), cow dung–rock phosphate (S4), cow dung–biochar (S5), and rock phosphate–biochar (S6). The results indicated that combination of six spores mycorrhizae/plant–cow dung 60 tons ha⁻¹–biochar 25 tons ha⁻¹ (M1S5) increased soil organic carbon (SOC) (235%), available P (675%), cation exchange capacity (CEC) (216%), total glomalin (101%), and easily extracted glomalin (69%), decreased exchangeable sodium percentage (66%), and increased absolutely for root infection and spore density than without mycorrhizae and a soil ameliorant (control). The lowest of SOC in non-mycorrhizae and rock phosphate, available P, CEC, root infection, spore density were found on the control, but the lowest of total glomalin and easily extracted glomalin were found on non-mycorrhizae–rock phosphate. The application of mycorrhizae, cow dung, and biochar improved the sandy soil characteristics.</p>

Researching the Possibility of Using Sediments in Forest Reclamation of Disturbed Lands

The research of the physico-chemical, biological and toxicological parameters of sediments and soils reclaimed by them, as well as the analysis of the growth of Scots pine seedlings, suggests that the use of sediments as a soil ameliorant at forest reclamation sites is advisable.
