ABSTRACT Biococotin is a fertilizer made from human feces and dried cocopit. The use of dried human feces and cocopit can be carried out on sandy land. This is because human feces are one of the feces that have good soil nutrient ability. Can be used as fertilizer on sandy land. Good plant nutrition will correlate with crop yields and farmer's income. Biococotin with manure has been used by farmers. Research carried out on sand farm farmers in Bengkulu Province discussed Lempuing Village, Bengkulu. The study was conducted for one month, June-July 2018. The process of collecting data was obtained from experimental results and interviews. Financial amount of funds needed to build and then carry out business activities. The results obtained from the costs incurred by biococtin are greater than those with manure. The entire competition meets eligibility, but nothing is feasible. This is due to high operational costs. The biggest outpouring of costs is the purchase of dry cocopit. This is because there is no dry cocopit in Bengkulu. The purchase of cocopit is carried out beyond the Bengkulu area at high prices.Keywords:  Biococotin, Finansial; Bengkulu. ABSTRAK Biococotin salah satu pupuk yang terbuat dari tinja manusia dan cocopit kering. Pemanfaatan tinja manusia kering dan cocopit dapat dilakukan di lahan berpasir. Hal ini dikarenakan tinja manusia merupakan salah satu kotoran yang memiliki kemampuan nutrisi tanah yang baik. Sehingga dapat dimanfaatkan sebagai pupuk pada lahan berpasir. Nutrisi tanaman yang baik akan berkorelasi dengan hasil tanaman dan pendapatan petani. Sehingga perlu dianalisis bagaimana perbandingan pendapatan pupuk biococotin dengan pupuk kandang yang selama ini digunakan oleh petani. Penelitian dilakukan pada petani lahan pasir di Provisi Bengkulu tepatnya Desa Lempuing, Bengkulu. Penelitian dilakukan selama satu bulan yaitu bulan juni-juli 2018. Proses pengumpulan data di dapatkan dari hasil eksperimaental dan wawancara. analisiss data aspek finansial (keuangan), jumlah dana yang dibutuhkan untuk membangun dan kemudian mengoperasikan kegiatan bisnis. Hasil yang di dapatkan yaitu biaya yang dikeluarkan biococtin lebih besar dibanding dengan pupuk kandang. Keseluruhan komoditas memenuhi kelayakan, akan tetapi komoditas kangkung perlakuan biococotin tidak layak. Hal ini disebabkan karna biaya operasional yang tingi.  Curahan biaya paling besar yaitu dalam pembelian cocopit kering. Hal ini dikarenakan tidak tersedianya cocopit kering didaerah Bengkulu. Sehingga pembelian cocopit dilakukan diluar daerah Bengkulu dengan harga mahal.Kata kunci:  Biococotin, Finansial, Bengkulu.

Vegetation coverage is a key variable in terrestrial ecosystem monitoring and climate change research and is closely related to soil erosion and land desertification. In this article, we aimed to resolve two key scientific issues: (1) quantifying the spatial-temporal vegetation dynamics in the Otindag Sandy Land (OSL); and (2) identifying the relative importance of climate factors and human activities in impacting vegetation dynamics. Based on correlation analysis, simple regression analysis, and the partial derivative formula method, we examined the spatiotemporal variation of vegetation coverage in the OSL, belonging to the arid and semiarid region of northern China, and their interaction with climate-human factors. The results showed that the vegetation coverage of the area showed a downward trend with a rate of −0.0006/a during 2001–2017, and gradually decreased from east to west. Precipitation was the main climate factor controlling the overall distribution pattern of vegetation coverage, while the human factors had a more severe impact on the vegetation coverage than the climate factors in such a short period, and the overall impact was negative. Among the human factors, population pressure, urbanization, industrialization, pastoral production activities, and residents’ lifestyles had a negative impact. However, ecological restoration polices alleviated the contradiction between human development and vegetation deterioration. The results of this article provide a scientific basis for restoring grassland systems in arid and semi-arid areas

Semi-arid region of Soil repair in Mine spoils is a problem of worthy of attention and research, this paper assesses Fuxin mining area and YuanBaoShan mining area for test site, five kinds of site types are divided based on the investigation of mine spoils damage situation, and testing each sitetype of soil physical properties and the change of soil nutrient systematically, and doing the five kinds of sitetypes’phytoremediation research based on it. The evaluation results indicate: Mine spoils soil along with the increasing length of stopping discharging the gangue, the soil physical and chemical characteristics improve gradually. Through the research of vegetation and soil interaction relations we get the best Reclamation vegetation types of the Mine spoils. Mine spoils is an important form of land degradation, is one of the major environmental problems of today's world. This paper assesses Fuxin mining area and YuanBaoShan mining area for test site, testing each site type of soil physical properties and the change of soil nutrient systematically, and on the basis of experiments, putting forward the best Reclamation vegetation types for mine spoils.

The nutrient accumulation curves of apple trees are good indicators of plant nutrient demand for each developmental stage. They are also a useful tool to evaluate orchard nutritional status and to estimate the amount of soil nutrient removal. This research aimed at evaluating the seasonality of nutrients in commercial apple orchards during the agricultural years of 1999, 2000, and 2001. Therefore, apple tree leaves and fruits of three cultivars 'Gala', 'Golden Delicious' and 'Fuji' were weekly collected and evaluated for fresh and dry matter, fruit diameter and macronutrient (N, P, K, Ca and Mg) and micronutrient (B, Cu, Fe, Mn, and Zn) concentrations. Leaf and fruit sampling started one or two weeks after full bloom, depending on the cultivar, and ended at fruit harvest or four weeks later (in the case of leaf sampling). In general, leaf concentrations of N, P, K, Cu, and B decreased; Ca increased; and Mg, Fe, Mn, and Zn did vary significantly along the plant vegetative cycle. In fruits, the initial nutrient concentrations decreased quickly, undergoing slow and continuous decreases and then remaining almost constant until the end of fruit maturation, indicating nutrient dilution, once the total nutrient accumulation increased gradually with fruit growth. Potassium was the nutrient present in highest quantities in apple tree fruits and thus, the most removed from the soil.
