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.

Yavatmal is one of the drought prone districts in Maharashtra state of India and has witnessed an agricultural crisis to the extent that hundreds of its farmers have committed suicides in recent years. Satellite data based products have previously been used globally for monitoring and predicting of drought, but not for monitoring their extreme impacts that may include farmer-suicides. In this study, the performance of the Soil Water Index (SWI) derived from the surface soil moisture estimated by the European Space Agency’s Advanced Scatterometer (ASCAT) is assessed. Using the 2007-2015 data, it was found that the relationship of the SWI anomaly was bit stronger (coefficient. of correlation = 0.59) with the meteorological drought or precipitation than with the agricultural drought or crop yields of major crops (coefficient. of correlation = 0.50).  The farmer-suicide rate was better correlated with the SWI anomaly averaged annually than with the SWI anomaly averaged only for the monsoon months (June, July, August, and September). The correlation between the SWI averaged annually increased to 0.89 when the averages were taken for three years, with the highest correlation occurring between the suicide rate and the SWI anomaly averaged for three years. However, a positive relationship between SWI and the suicide rate indicated that drought was not a major factor responsible for suicide occurrence and other possible factors responsible for suicide occurrence need to examine in detail.

SUMMARYThe transition from conventional to organic farming is accompanied by changes in soil chemical properties and processes that could affect soil fertility. The organic system is very complex and the present work carries out a short-term comparison of the effects of organic and conventional agriculture on the chemical properties of a silty loam soil (Xerofluvent) located in the Guadalquivir River Valley, Seville, Spain, through a succession of five crop cycles over a 3-year period. Crop rotation and varieties were compared in a conventional system using inorganic fertilizer and two organic systems using either plant compost or manure. At the end of the study, organic farming management resulted in higher soil organic carbon (OC), N and available P, K, Fe and Zn. The available Mn and especially Cu values did not show significant differences. In general, treatment with manure resulted in more rapid increases in soil nutrient values than did plant compost, which had an effect on several crop cycles later. The present study demonstrated that the use of organic composts results in an increase in OC and the storage of nutrients, which can provide long-term fertility benefits. Nevertheless, at least 2–3 years of organic management are necessary, depending on compost characteristics, to observe significant differences. Average crop yields were 23% lower in organic crops. Nevertheless, only two crops showed statistically significant differences.

A novel patented method (PCT/IB2012/001157: Squartini, Concheri, Tiozzo, University of Padova) and the corresponding application devices, suitable to measure soil fertility, are presented. The availability or deficiency of specific nutrients for crops is assessed by monitoring the kinetics of progressive weakening of cotton or silk threads due to in situ microbial activity. The method is based on a nutrient-primed incremented substrate degradation principle. Threads are buried as is or pre-impregnated with N or P solutions, and the acceleration of the degradation rate for the N-supplemented or P-supplemented thread, in comparison to the untreated thread, is proportional to the lack of the corresponding nutrient in that soil. Tests were validated on corn crops in plots receiving increasing fertilizer rates in a historical rotation that has been established since 1962. The measurement carried out in May significantly correlated with the subsequent crop yields recorded in October. The analysis allows an early, inexpensive, fast, and reproducible self-assessment at field level to improve fertilization rates. The device is envisaged as a user-friendly tool for agronomy, horticulture, and any environmental applications where organic matter cycling, soil quality, and specific nutrients excess or deficiency are critical considerations.

AbstractWe tested the usefulness of mulching with polypropylene landscape fabric and compost as alternatives to bare soil for growing red cabbage and watermelon. Polypropylene landscape fabric has features similar to the polyethylene film that is popular for commercial vegetable production, but its durability permits multi-year use, which would reduce excessive waste produced from the typical single-season use of polyethylene film. On the other hand, compost used as mulch enhances soil development while providing weed suppression and water retention, among other benefits. Yields of red cabbage and watermelon were measured for 3 years in plots receiving either 10 cm compost, landscape fabric, or no mulch. Labor associated with crop production and weed suppression was measured as time spent on each task. Cabbage yields over 3 years followed the treatment order of compost > no mulch > fabric, while for melon yields it was compost > fabric > no mulch. Total labor required over 3 years for both crops, according to treatments, was fabric > compost > no mulch. However, labor for the fabric-treated plots dropped sharply after the first year, because fabric was left in place after initial placement. Labor for unmulched cabbage plots increased over time due to weeding and transplanting; labor for unmulched and compost-mulched melon plots increased for the same reasons. Compost provided the highest crop yields with a moderate labor investment. Surface-applied compost substantially increased underlying soil nutrient levels. The study indicates that polypropylene landscape fabric may be a potential alternative to the more traditional polyethylene film for permanent beds in vegetable production.

In Morocco, intensive agriculture with deep tillage and soil inversion caused rapid soil structure deterioration with loss of soil organic matter content. This practice leads to a decrease in soil fertility, a degradation of the soil physical properties and a reduction of crop yields in different soil types, such as Vertisols. In fact, Vertisols (or Tirs as vernacular name) are among the most productive soils in Morocco, but they are also susceptible to compaction and reduced water infiltration due to intensive tillage. No-tillage (NT) is commonly promoted as a management practice capable of offsetting soil carbon depletion, improving aggregation, enriching the soil nutrient pool and enhancing crop productivity in many parts of the world. However, the influence of the NT system as compared to the conventional tillage (CT) system on physical, chemical and hydrodynamic soil properties was not yet well studied in the semi-arid environment of Morocco where rainfall ranges from 350 to 600 mm. This research focused mainly on those parameters with important agronomical or environmental impact: bulk density (Db), soil strength assessed using cone index (CI), hydraulic conductivity (K), sorptivity (S), soil water potential (SWP), soil organic carbon content or stock (SOCc or SOCs), runoff, soil loss, soil CO2 emission and crop yield.

Crop Failure

Usually crop failure due to moisture shortage in soils is very much common due to high evaporation. Sometimes famers try to combat this problem by using mulches of crop residues in the study area. However, this is also highly challenged shortage because the crop residues used as feed for animals. Therefore, using the advantage and opportunity of cover legumes as an intercrop is the solution of the problems simultaneously in addition to their contribution improving soil nutrient balance and other many fold benefits. Therefore, this study aimed for evaluating the effect of maize-legume covers intercropping on soil moisture improvement and crop yield in moisture stress areas of the study area. The entire grain yield of maize and legumes, as well as soil moisture data were collected. The result on soil moisture revealed that intercropping of maize with cowpea had better soil moisture contents during active crop development (15.98%) and after harvest (16.70%) in average as compared to the others. The current finding also showed that adopting intercropping of maize with cowpea-boosted yield by 5256.24 kg ha-1 maize and 977.45 kg ha-1 cowpea in average with higher moisture improvement as compare to the other treatments. Therefore, intercropping of maize with cowpea is important to farmers since it would provide additional crop yield with the same piece of land. However, to get considerable changes on soil and water balances, other soil physic-chemical properties and crop yields, conducting similar studies in more than two years period at permanent field plots is paramount in the future.

AbstractThe North Dakota Cloud Modification Project was established in 1951 to reduce severe hail damage and increase precipitation in specific counties in North Dakota. Every year, participating counties receive cloud seeding treatment during the months of June, July, and August. Although some atmospheric studies have examined the efficacy of the treatment, few have used statistical procedures to determine how the program affected crop yields and crop losses. We use the panel nature of historical cloud seeding participation and crop data to estimate a two-way fixed effects regression with county-specific time trends to examine the effect of cloud seeding on wheat and barley yields. In addition, we use federal crop insurance data to estimate the effect of cloud seeding on losses for those same crops. Our evaluation indicates that the cloud seeding program had significant positive effects on crop yields and improved loss ratios.

<p>Sandification has become a major obstacle to China’s regional farmland protection, economic development and ecological civilization construction. Sandy land consolidation technologies and sustainable utilization modes will provide farmland for modern agricultural development. We introduced structural consolidation theory to sandy land rehabilitation from the aspects of soil body building, soil layer reconstruction and soil quality improvement. Filed experiments were conducted in Mu Us Sand Land to explore the effects of dry mixtures of guest material (red clay and loess) and sand at four volume ratios (1:1, 1:2, 1:3 and 1:5) on crop yield, soil properties and maize root growth. Red clay treatments had higher sandy land structural consolidation engineering costs and crop yields than loess treatments. Red clay and loess had significant promotion of maize and soybean yields at volume ratios of 1:3. The maximum potato yield is 42501 kg ha<sup>-1</sup> and 37332 kg ha<sup>-1</sup> in red clay treatment at volume ratio of 1:5 and in loess treatment at volume ratio of 1:5, respectively. Red clay and loess significantly increased clay and silt ratio and regulated the soil total nitrogen concentration and soil organic matter content during the critical growth stage of maize. Lowest root biomass in surface soil and lowest surface/subsoil root biomass ratio mediated maize growth in red clay treatment at volume ratio of 1:3. Red clay can be used to consolidate sandy land and develop modern agriculture in the long-term according to the engineering costs and crop yields. Enhanced land productivity, increased land transfer rent and extra wage income provide a stainable and stable increase in households’ income for escaping from poverty. Spatial overlap between red clay with sandy land makes red clay as a new available material for sand land consolidation and utilization from China to global scale. China’s sandy land structural consolidation engineering and sustainable utilization practices will contribute prescriptions to global desertification fighting and rural poverty alleviation. Regional water resource carrying capacity evaluation should be emphasized before sandy land structural consolidation engineering popularization.</p>
