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.

The Impact

This paper develops a lexicographic optimization model to allocate agricultural and non-agricultural water footprints by using the land area as the influencing factor. An index known as the water-footprint-land density (WFLD) index is then put forward to assess the impact and equity of the resulting allocation scheme. Subsequently, the proposed model is applied to a case study allocating water resources for the 11 provinces and municipalities in the Yangtze River Economic Belt (YREB). The objective is to achieve equitable spatial allocation of water resources from a water footprint perspective. Based on the statistical data in 2013, this approach starts with a proper accounting for water footprints in the 11 YREB provinces. We then determined an optimal allocation of water footprints by using the proposed lexicographic optimization approach from a land area angle. Lastly, we analyzed how different types of land uses contribute to allocation equity and we discuss policy changes to implement the optimal allocation schemes in the YREB. Analytical results show that: (1) the optimized agricultural and non-agricultural water footprints decrease from the current levels for each province across the YREB, but this decrease shows a heterogeneous pattern; (2) the WFLD of 11 YREB provinces all decline after optimization with the largest decline in Shanghai and the smallest decline in Sichuan; and (3) the impact of agricultural land on the allocation of agricultural water footprints is mainly reflected in the land use structure of three land types including arable land, forest land, and grassland. The different land use structures in the upstream, midstream, and downstream regions lead to the spatial heterogeneity of the optimized agricultural water footprints in the three YREB segments; (4) In addition to the non-agricultural land area, different regional industrial structures are the main reason for the spatial heterogeneity of the optimized non-agricultural water footprints. Our water-footprint-based optimal water resources allocation scheme helps alleviate the water resources shortage pressure and achieve coordinated and balanced development in the YREB.

The application of organic fertilizer, especially manures, for crop production has long-term effects for soil nutrients availability and improvement of soil structure. The improvement of soil properties involves interactions of various types of microorganism in the soil. The research aimed to study the effects of different types of manures on the diversity of functional soil microbes and its effects on organic green mustard production. The experiment was conducted at IPB organic research field, Cikarawang, Darmaga, Bogor, from April to June 2015. The experiment used a randomized complete block design with two factors; the first factor was types of manure, i.e. chicken, cow, and goat manures; the second factor was manure rates, i.e. 0 and 10 ton.ha-1, so there were six treatments in total, replicated three times. The results showed that chicken manure application resulted in a higher mustard green yield and soil-P content than application of goat manure. The addition 10 ton.ha-1 of manures increased C-organic, N, K, and C/N ratio in soil significantly, but mustard green production was not affected. The diversity of microbe population of the soil treated with all types of manures was high. The addition 10 ton.ha-1 of manures decreased the total number of microbes, but increased the number of cellulose-degrading microbes. The population of cellulose-degrading and phosphate-solubilizing microbes in the soil applied with cow manure was higher than those applied with the other manures.

By continuous and rapid growth in industrialization as well as population, the agricultural lands are also becoming less and less continuously day by day which results in increase in the population of small land holders. In addition to this, because of continuous decreasing production the youth of the villages are also migrating in big cities for the employment, resulting decreasing manpower essential to perform various seedbed operations in the villages. Hence, it is the need of time for small farmers having small agricultural land and having less crop production to introduce the cost-effective farm mechanization so that they can improve production rate. Rotavator is the best option available to achieve this landmark as it is already proved that seedbed prepared by using rotavator gives highest benefit to cost ratio. For this experimental study the whole land of 9 acre area is divided into 18 plots of equal size in area. The combination of method of seedbed preparation and use of fertilizers were the preliminary criteria. The categories of fertilizer according to quantity are discussed earlier which are 50kg, 35kg and 65kg per acre respectively. The quantities of organic fertilizer used are 45kg and 60kg per acre of agricultural land for both seedbeds which are prepared manually and by using rotavator. The highest production of Pigeon Pea was obtained of 814kg was from the plot whose seedbed is prepared by using agricultural machine called rotavator and organic fertilizer; next highest production is obtained of 802 kg from the plot whose seedbed is prepared by using rotavator and the fertilizer used was chemical fertilizer. The minimum production of Pigeon Pea which is 690 kg was obtained in the plot whose seedbed was prepared manually and chemical fertilizer was used.

Agrotourism is a tourism activity that combines plantation or agricultural activities by offering unique experiences to visitors. Indonesia, which has natural resources in the plantation and agricultural sectors, provides great opportunities for the community, one of which is implemented by the Mulia Asih Farmer Group in Humbang Raya Village, Central Kalimantan. Agricultural and plantation activities require fertilizer as an important component in increasing crop production, and there are even demands for environmentally friendly use of organic fertilizer or compost as an advantage so that people innovate to create organic fertilizer processing machines from the surrounding environment. This article uses a qualitative approach to discuss the findings of local communities and analyze them with the copyright law which regulates the copyright of photographic works and portraits taken without permission. Article 12 paragraph (1) of the Copyright Law regulates economic rights to portraits, there must be written consent from the person being photographed or their heirs for reproduction, distribution, announcements, commercial use, and/or communications used for billboards, advertisements, banners, pamphlets and more. The results of this study show that the public has not realized unintentional errors due to limited information so that the innovations made are claimed to be their own work even though they have previously been discovered by other communities.

AbstractRegions with intensive agriculture often encounter environmental problems caused by nutrient excess of agro-food-waste systems that have become increasingly linear over previous decades. In this study, nitrogen (N), phosphorus (P), potassium (K) and carbon (C) flows in the whole agro-food-waste system of district Cleves in Germany were quantified simultaneously using substance flow analysis. Moreover, nutrient use inefficiency hotspots were identified to establish options to improve nutrient self-sufficiency as a first step towards nutrient circularity. Data on mass flows and nutrient contents was acquired for the year 2016 from stakeholders, statistical databases, literature and modelling. Organic C was included for flows with potential as organic fertilizer. Results show that animal production drives the nutrient flows in the export-oriented district, with feed import, manure application and losses from housing and manure storage accounting for 40, 45 and 60% of all N, P and K flows, respectively. In particular agriculture is responsible for N losses, with 150 kg N lost ha−1 agricultural land. Crop production surplus and with that soil accumulation of P and K are 515 t and 4100 t respectively. Stoichiometry of N:P:K:C in the different organic materials does not allow direct application and meeting crop requirements without exceeding demand of especially P. Processing of biomass is therefore required. Based on mass, especially manure holds potential for processing into bio-based fertilizers. To improve nutrient cycling and soil C conservation, being an important element for a sustainable agricultural sector, local balances between crop and animal production need to be considered.

Along with the increasing the of the land-use change of the fertile agricultural land in Java, the better awareness has been subjected to the importance of function peat land for agricultural development. Cassava (Manihot esculenta Crantz) is a tuber plant that potentially developed as important carbohydrate source. The objective of this research was to identify superior cassava variety candidate of selected cassava developed by of Research Centre Biotechnology, LIPI which has high adaptation capability and yield in Central Kalimantan peat land area. This research was conducted from July 2010 through May 2011 in Central Kalimantan Province (Kalampangan dan Pulang Pisau in total of area 1.5 and 2.25 ha respectively). There were three genotypes of cassava tested, i.e. Iding (high amylose), Gebang (low amylose), and Menti (high starch) compared to Adira 4 (35 ton/ha) and Darul Hidayah (102.1 ton/ha). The variables observed were plant height (cm) and tuber weight (grams). Observations were conducted at the age of 10 months. Data was analyzed using SPSS version 16.0. The results showed that the plant height and yield were higher in Pulang Pisau than Kalampangan even though the difference is not significant (P ≤ 0,05). Darul Hidayah has highest plant height and yield, 229.8 cm and 2271 g respectively among other genotypes/varieties grown at Pulang Pisau even though the value was not significant, whereas in Kalampangan, Darul Hidayah showed the lowest yield (670 g). Based on the data obtained, the Darul Hidayah variety can be cultivated by farmers in Pulang Pisau peat land to fulfill the availability of superior cassava seedlings for food, feed and industry.

Pepper Plants

Farmers generally plant pepper on ultisol soil. Ultisol soil is classified as acid mineral soil which has a wide distribution, but has the potential to develop agricultural land including pepper plantations. The tendency of land used for agricultural activities shows a decrease in soil fertility, indicated by the occurrence of erosion, imbalance of nutrients present in the soil and stronger soil dependence on fertilizer, as well as lower crop production. The research aims to find out the characteristics of pepper land, productivity, potential land for the development of pepper plants in Muara Badak District. This research was carried out using survey methods with stages including; overlaying land maps, interviews, secondary data inventory, in the form of data on the number of farmers, land area, production and cultivation techniques, and analysis of soil samples in the laboratory. The results showed that the population / ha of pepper plants was different for each farmer, where the spacing was 110 x 110 cm, 120 x 120 cm, 130 x 130 cm and 140 x 140 cm with a population between 1300 - 4500 staples / ha. Farmers generally use lodrin organic fertilizer, but are not carried out intensively, and the land management system does not pay attention to the aspect of soil conservation, farmers' land has been cultivated for generations without using terraces and soil cover. The tendency of nutrient loss on the land is quite high because the land is located on a hill and is quite steep at 16-40% slope. Pepper productivity in the study area is quite high, with an average of 1,437 kg / ha. The highest productivity in Salo Palai village reached 1970 kg / ha, while the lowest in Batu Batu village was 830 kg / ha. The results of soil analysis in the two study locations that the content of the element N was classified as medium, the total K was classified as high to very high. pH and CEC are low, this can affect nutrient absorption, so that lime is needed and the addition of organic matter if fertilization is carried out.
