Ultisol soil is a less fertile soil characterized by low soil fertility rate, high acidity with pH<5, high Al saturation. This land has an area of 25% of the total land area of Indonesia. Riau Island is one of the provinces dominated by Ultisol land, so many land is not productive to use as agricultural land. This research was conducted to look at the characteristics of red soil in the agricultural land in Batam City after mixed with organic material in this case which is used is goat manure and chicken manure. From the results of research, the addition of goat manure and chicken manure that is incubated for 30 days can already give changes to the physical and chemical character of the soil, such as soil becoming more loose, having higher water content, increasing soil C organic, Nitorgen, P2O5, K, Mg, and Mn, able to reduce Fe levels in the soil. The addition of chicken manure can increase the available of Phosphate, gives K, Mg, and Mn higher than compared mixing blanko with goat manure. The addition of goat manure can increase the total of C organic and N in the soil is higher than chicken manure.

<p>Most of agricultural lands in Pasir Eurih Village are paddy field simple irrigation system, while most of them in Sukajadi Village are upland. Farmers in both villages are used to composting organic residues, but the composts was not used maximally. The aim of the IbM activities was: (1) To guide our partners to produce better quality of composts sustainable; and(2) To motivate the community of peasant  using composts for their farm. The best compost resulted by IbM-3 guidance was made from rice straw, leaf litter, and chicken manure mixed with rice husk as their bedding by ratio of 3:2:1:1. This compost contained macronutrients (N, 0.56%, P<sub>2</sub>O<sub>5 </sub> 1.09%, K<sub>2</sub>O 1.44%, Ca 5.72%, Mg 0.43%, and Na 0.08% respectively), micronutrients Fe 5.309 ppm, Mn 342 ppm, Cu 42 ppm, Zn 69 ppm, and B 33 ppm respectively), and heavy metals of Pb was 4.8 ppm and Cd 0.04 ppm. The addition of 3-4 ton/ha of this compost into paddy soil could reduce chemical fertilizers up to 50%. The addition of 3 ton/ha of this compost to upland soil planted by sweet corn produce same with application of chicken manure bedding or goat manure. Socialization of the benefit of using compost in increasing the soil fertility and crop yield have raised the peasant’s knowledge. It was showed by the mean value of this post test raised 19.67 points for fertilizer and soil fertility matter and 16.63 points for organic materials or natural fertilizers matter.</p><p> </p>

It has long been recognized that human activity chemically modifies the composition of the soil. This is especially true around ancient settlements that were occupied for relatively long periods of time. In areas that humans have inhabited, soil fertility is higher than in uninhabited areas because of an increase in plant nutrients derived from human and animal waste. Deep dark soils that contrast with neighboring lighter colored soils can define areas of intensive occupation with great precision. Phosphate (PO4-3), an important plant nutrient, is highly concentrated at ancient sites and makes for an increased soil fertility. Arab farmers in the Near East have been known to use soils excavated from archaeological sites to fertilize their agricultural land. The soil phosphate has been derived from animal and human excreta and bones and dead bodies. Phosphate will be especially concentrated where animals have been enclosed. Phosphate found in the soil can be bound chemically in a variety of ways. Since the soil is a dynamic system, its physical and chemical nature will constantly alter over time depending on local and temporal equilibria conditions. The first studies of soil phosphate were by agronomists as a tool for agriculture. The observation that human occupation increased the phosphate concentration was noted at least by 1911 in Egypt as a result of agronomic studies. O. Arrhenius, a Swedish agronomist, made the first attempt to apply phosphate studies to archaeology, in a series of papers beginning in 1929. He concluded that phosphate concentrations could be used to locate abandoned settlement sites, even where no visible evidence remained. Thus, the initial application of soil phosphate analysis to archaeology was as a geochemical exploration tool to locate ancient settlements. Human occupation should increase not only the phosphate found in the soil but also the nitrogen and carbon. These additions result from the decomposition of organic matter, principally human and animal remains and excreta. In desert or agricultural land, phosphorus in the soil ranges from 0.01% to 0.2% in the uppermost 10 cm and nitrogen ranges from 0.1% to 1%.

The North Sumatera province has the fifth largest goat population in Indonesia after Central, East, Lampung and West Java. Meanwhile, solid and liquid goat manures have great potential as a source of organic fertilizer. Therefore, this study aims to examine the potential of goat manure as a source of organic fertilizer and its role in improving soil quality, growth and crop production. The data were collected from the Central Bureau of Statistics and the results of previous studies. Furthermore, the potential of goat manure was calculated by multiplying the total goat population in North Sumatra by the goat manure production /head/day and converted to one year. The parameter measured was the total goat population in North Sumatera, goat manure production/head/day, and the covered agricultural land area. The results showed that goat manure only fulfilled 3.69% of the agricultural land area in North Sumatera. In addition, the case study in Deli Serdang District showed that the application of goat manure compost with biourine and balanced inorganic fertilizers increased red chilies’ productivity by 46%. Therefore, it was concluded that the potential of goat manure as organic fertilizer is still very low.

Dusun Sugihan has thewidest area of paddy field in Desa Sumberejo with post-harvest rice straw of 12 tons/ha.Those rice straw have not used optimally.Ifleft untreated, it can spoil the aesthetics of the environment, generates odor and becomes a den of disease vectors. The purpose of the present study was to determine the fermentation process of composts and the quality of composts produced with regard to temperature, humidity, pH, water content, C/N ratio and levels of Pb in composts.The present study was a pre-experiment usinga statistical group comparison. Data were analyzed descriptively in order to describe the results of the field inspection and laboratory testing in accordance with SNI 19-7030-2004 on Compost Quality Standards. Results of this 8-wk study showed that the fastest composting time was for the compost with chicken manure was the activator at a dose of 30% for 3 weeks.In terms of compost quality, which includes temperature, pH, humidity, water content and levels of Pb,all of the composts fulfilled the requirements. However, with regard to C/N ratio,those composts with activator of 10% cow manure,10% goat manure and no manure did not fulfill the requirements with a C/N ratio of 27.36, 23.64 and 26.75, respectively. Therefore, it is recommended to make composts using manure as an activatorat a dose ≥20% in order for fulfillment of C/N ratio and shorter composting time.

Soil, itself means Soul of Infinite Life. Soil is the naturally occurring unconsolidated or loose covering on the earth’s surface. Physical properties depend upon the amount, size, shape, arrangement, and mineral composition of soil particles. It also depends on the organic matter content and pore spaces. Chemical properties depend on the Inorganic and organic matter present in the soil. Soils are the essential components of the environment and foundation resources for nearly all types of land use, besides being the most important component of sustainable agriculture. Therefore, assessment of soil quality and its direction of change with time is an ideal and primary indicator of sustainable agricultural land management. Soil quality indicators refer to measurable soil attributes that influence the capacity of a soil to function, within the limits imposed by the ecosystem, to preserve biological productivity and environmental quality and promote plant, animal and human health. The present study is to assess these soil attributes such as physical and chemical properties season-wise.

Soil C Sequestration

&lt;p&gt;Reducing greenhouse gas (GHG) emissions in to the atmosphere to limit global warming is the big challenge of the coming decades. The focus lies on negative emission technologies to remove GHGs from the atmosphere from different sectors. Agriculture produces around a quarter of all the anthropogenic GHGs globally (including land use change and afforestation). Reducing these net emissions can be achieved through techniques that increase the soil organic carbon (SOC) stocks. These techniques include improved management practices in agriculture and grassland systems, which increase the organic carbon (C) input or reduce soil disturbances. The C sequestration potential differs among soils depending on climate, soil properties and management, with the highest potential for poor soils (SOC stock farthest from saturation).&lt;/p&gt;&lt;p&gt;Modelling can be used to estimate the technical potential to sequester C of agricultural land under different mitigation practices for the next decades under different climate scenarios. The ECOSSE model was developed to simulate soil C dynamics and GHG emissions in mineral and organic soils. A spatial version of the model (GlobalECOSSE) was adapted to simulate agricultural soils around the world to calculate the SOC change under changing management and climate.&lt;/p&gt;&lt;p&gt;Practices like different tillage management, crop rotations and residue incorporation showed regional differences and the importance of adapting mitigation practices under an increased changing climate. A fast adoption of practices that increase SOC has its own challenges, as the potential to sequester C is high until the soil reached a new C equilibrium. Therefore, the potential to use soil C sequestration to reduce overall GHG emissions is limited. The results showed a high potential to sequester C until 2050 but much lower rates in the second half of the century, highlighting the importance of using soil C sequestration in the coming decades to reach net zero by 2050.&lt;/p&gt;

Analysis Of Dynamics

The main trends in changing the land use structure in the territory of the Klyazma River basin were de-scribed in the article. Using GIS technologies and remote sensing data the areas of land with different land use regimes in the studied territory were determined in the period from 2001 to 2019. The indices of LAI and FPAR phytoproductivity for the territory of the Klyazma basin as a whole, and for each basin included in it were determined. The analysis of the dynamics of changes occurring in the structure of land use is carried out. For the territory of Vladimir region, which is a part of the Klyazma River basin, an assessment of soil types distribution over occupied area was carried out. An integral indicator of soil fertility was calcu-lated on the basis of statistical data of agrochemical indicators. The fraction of fallow lands decreased by 2019 and it amounts 33.76% of the total area of the studied territory. The fraction of mixed forests increased from 38.48% in 2001 to 44.50% in 2019 due to the formation of fast-growing tree species shoots on fallow lands. The area of meadow vegetation for the period from 2015 to 2019 decreased by 3.5%, from 4 276 to 3 121 km2, due to agriculture degradation and a significant decrease in livestock grazing. The indicator of soil fertility for the Klyazma basin was 0.74, which is a high indicator. It is established that the most active decrease in the agricultural land area occurs in the central, north-western and western parts of the river basin.
