The Relationship

Take the test zone 110 sampling plots of soil nutrient content as the research data, to study the correlation between the soil nutrient content and the corn yield. It used the grey system theory to analysis the correlation between the content of soil nutrient, and established GM (1, N) prediction model. Soil nutrient correlation degree analysis showed that the correlation coefficient of available phosphorus and available potassium were 0.4742, 0.4492, it has a significant effect on the corn yield, the average prediction error of the GM (1, N) model was 7.38%. The model reflected the relationship between soil nutrient content and the corn yield well; it can be used to predict the yield test area.

SUMMARYStudies of the relationship between yield and content of N, P and K in the ear leaf of eight varieties of Nigerian maize, tested for three growing seasons, indicated that the varieties have different critical nutrient levels, although the values obtained for individual varieties were not significantly different from the pooled average critical level for any of the nutrients. The critical levels ranged from 2·85 to 3·19% N, 0·20 to 0·27% P and 2·06 to 2·60% K, while their pooled averages were 3·10% N, 0·23% P and 2·44% K.High ear leaf nutrient content was not a guarantee of high grain yield, and ear leaf nutrient values of low-yielding varieties were similar to those of the high-yielding varieties.

The Relationship

In this study, it was aimed to determine the relationship between soil algae and physico-chemical structure of soil. Algae composition and some soil quality parameters from 12 sampling stations were investigated between March 2019 and May 2019 in Kocaeli. Physico-chemical properties that reflect soil nutrient content and fertility status (pH, conductivity, salinity, CaCO3, organic matter, saturation, P2O5 and K2O) were determined using standard physicochemical techniques. Average in soil parameters were determined as pH: 8.06, conductivity: 5.79 µmhos / cm, salinity: 0.22 ‰, CaCO3: 9.98%, organic matter: 1.70%, saturation: 59.55%, P2O5: 3.16 kg / da, K2O: 93.92 kg / da. Algal flora of Kocaeli province was a total of 30 taxa, 14 taxa of Bacillariophyta, 3 taxa of Chlorophyta, 1 taxa of Charophyta and 12 taxa of Cyanobacteria were identified. The determined as the Chroococcus cohaerens, Limnococcus limneticus, Phormidium nigroviride, Oscillatoria limosa, Gomphonema olivaceum, Hantzschia amphioxys and Nitzschia brevissima most dominant taxa. These taxa have been identified in stations with high industrial activity. Bacillariophyta taxa were found in all months due to their ecological tolerance, while other species belong to spring. In this study, the species diversity were found similar in research stations.

Main Requirement

India is an agricultural country. 70% of people do this. The main requirement within the agriculture field is water and manpower. Nowadays the foremost problem lies in agriculture is water scarcity, manpower, funds, etc. To overcome these problems we've to develop an automation irrigation system using IoT. This technology is employed for creating systems automated using sensors like DHT11, Soil Moisture sensor, some hardware parts, and software. The PH sensor is additionally wont to analyze soil nutrient content present within the soil in real-time and therefore the PH sensor is employed to work out the Ph value of the soil. Monitoring of those provides the right fertility to the soil depending upon the soil nutrients. To provide quality crops supported temperature, humidity, soil moisture, and its nutrient level content and Ph. factor, it has also been maintained. The real-time result will be generated. The generated results PDF are going to be sent to the person through email or web SMS. The overall cost required should be low enough in order that every one can afford it.

Use Of Internet

Smart Agriculture now-a-days reducing various problems in farming. Farmers get required information and relative data to monitor the plants growth by the use of “INTERNET OF THINGS (IOT)”, which connects the different sensors, actuators and other embedded devices. To provide quality crops based on soil nutrient level and its moisture content along with Ph. factor, also been maintained. Hence, in this project all those parameters are detected and controlled with the help of micro controller. Humidity sensor to detect the moisture content, where colour sensor is used to determine the percentage of soil nutrients (N2 , P4 &K). It will analyse soil nutrient content present in soil at real time and Ph. sensor is used to determine the Ph value of the soil. Monitrring of these it provides the proper fertility to the soil depending upon the soil nutrients. GSM is used to display the information to the farmers. Thus it reduces the growing of husk in terms of wastage and thereby getting good quality and healthy crops.

Penelitian ini bertujuan untuk membandingkan kondisi edafik, hubungan antara kondisi edafik dan keanekaragaman organisme tanah, serta perbedaan keanekaragaman organisme tanah pada berbagai ekosistem rhizosfer gulma Siam (Chromolaena odorata) yang tumbuh di lahan vulkanik, pesisir, dan karst. Penelitian dilakukan dengan mengambil sampel tanah dari ekosistem rhizosfer gulma Siam di lahan vulkanik, karst, dan pesisir Daerah Istimewa Yogyakarta; mengamati komposisi organisme tanah di laboratorium, yaitu collembola, nematoda, dan mikoriza. Hasil penelitian menunjukkan bahwa tanah pada rhizosfer gulma Siam yang tumbuh di lahan karst menunjukkan tingkat kesuburan tertinggi yang ditunjukkan oleh kandungan N, K, dan C-organik tanah, sedangkan tanah pesisir memiliki kandungan P tertinggi. Tekstur tanah pada rhizosfer gulma Siam lebih berpengaruh terhadap keanekaragaman organisme tanah dibandingkan kandungan hara tanah dan sifat tanah lainnya yang diteliti. Keragaman organisme tanah rhizosfer gulma Siam lebih besar di lahan pesisir dibandingkan di lahan karst dan vulkanik. Implikasi dari hasil tersebut adalah bahwa tanah dengan tekstur berpasir akan lebih bermanfaat bagi pertumbuhan gulma Siam dengan keanekaragaman organisme rhizosfer yang lebih tinggi.ORGANISM DIVERSITY IN THE RHIZOSPHERE OF SIAM WEEDS IN VOLCANIC, COASTAL AND KARST LANDThe research aims to compare the edaphic condition, the relationship between the edaphic condition and soil organism diversity, and the differences of soil organism diversity in different rhizosphere ecosystems of Siam weed growing in volcanic, coastal and karts areas. The research was conducted by taking soil samples from the Siam weed rhizosphere ecosystems in volcanic, karst and coastal areas of the Special Region of Yogyakarta and observing the composition of the soil organisms in the laboratory, including collembola, nematode, and mycorrhiza. The results find that soil from rhizosphere of Siam weed growing in karst area shows the highest level of fertility indicated by the N, K, and C-organic contents of the soil, whereas soil from coastal area has the highest P content. Soil texture in the rhizosphere of Siam weed has more effect on the diversity of soil organisms than the soil nutrient content and other soil properties investigated. The diversity of soil organisms of Siam weed rhizosphere is greater in coastal area than those in karst and volcanic areas. The implication of the results is that soil with a sandy texture will be more beneficial for the growth of Siam weed with a higher diversity of rhizosphere organisms

In March 1992 treatments were established in a split plot design to compare vegetable yield and nutrient buildup effects of 94 kg of 34-0-0, 1345 and 2692 kg/ha spent poultry litter under fallow or wheat rotation cover. The 2692 kg litter treatment caused a nonsignificant decrease in `Crimson Sweet' watermelon yield. Wheat was planted on half the plot area in September 1992 and harvested in March 1993. Fertilizer and litter treatments were reapplied in April and `Merit' sweet corn was planted. Corn plant growth was more vigorous and yield was significantly higher in fallow plots irrespective of litter treatment. Sweet corn yield was highest in plots treated with 2692 kg liter/ha. NO3, K, SO4, and Mg content of the top 30 cm of soil was decreased by wheat. Soil nitrate level remained below the pretreatment level after the first year except for the 2692 kg litter/fallow treatment. Soil P at the 0-30 cm depth remained the same as or higher than the initial level in all treatments. Soil K content exceeded initial test levels in all fallow treatments and one wheat treatment.
