ABSTRACT The performance of three field kits was compared using prepared diesel fuel-in-sand samples and environmental field samples. The field kits were the EnviroGard Petroleum Fuels in Soil Test kit (EnviroGard, Millipore Canada, Mississauga, Ontario), PetroFlag Hydrocarbon Test Kit for Soil (Dexsil, Hamden, Connecticut), and a modified version of the method for oil and grease and petroleum hydrocarbons solvent extraction with infrared (IR) analysis (Buck Scientific, East Norwalk, Connecticut). The EnviroGard kit was affected by the sample matrix and was not capable of detecting the petroleum concentration. The Petroflag kit tended to generate results higher than the accepted concentration. The IR method was the most sensitive and produced values similar to the accepted concentration data.

Soil testing is an important component of a plant nutrient management program for farmers, home gardeners, and agricultural service personnel. Results from five commercially available colorimetric soil test kits were compared with standard laboratory analyses for pH, nitrate–nitrogen (NO3), phosphorus (P2O5), and potassium (K2O) content for Salinas clay loam soil with three cropping histories. The kits ranked in accuracy (frequency of match with analytical laboratory results) in the following sequence: La Motte Soil Test Kit, Rapitest, Quick Soiltest, Nitty-Gritty, and Soil Kit at 94%, 92%, 64%, 36%, and 33%. NO3 was most accurately determined by Rapitest and Quick Soiltest, P2O5 by Rapitest, and pH by La Motte Soil Test Kit. K2O was determined with equal accuracy by all but Soil Kit. The composition of the extractants may be an important factor affecting the accuracy of the test kit. For example, all kit extractants for K2O were composed of the same chemical and matched analytical laboratory results 82% of the time. By contrast, kits using an acid-based extractant for NO3 analysis more frequently matched the analytical laboratory results than kits using a zinc-based extractant (P ≤ 0.0001). La Motte Soil Test Kit had the largest range of pH measures, whereas Rapitest was relatively easy to use and interpret and is a practical choice for home gardeners or landscapers; both were more than 90% accurate for this soil type. Although an important limitation of commercial test kits is the approximate or categorical value of nutrient content (i.e., low, medium, high), accurate test kits can yield results quickly and economically for improved nutrient management.

An alternatif way to determine soil fertility level as well as to recommend fertilizer application is by using soil test kit. The kit can measure P and K status of soils as well as the pH value. The research was aimed to evaluate soil fertility level of paddy soil and to determine fertilizer recommendation for rice (variety ? IR64) having 5 t mill-dry seeds/ha at the soil in Kedurang Ilir and Seginim, South Bengkulu. Soil samples were collected in 24 villages in the area, then they were analyzed using the Test Kit. The results showed that (1) fertility level of paddy soil in Seginim was higher than that in Kedurang Ilir, (2) there were 4 packages of fertilizer doses (250- 100-100; 200-75-100; 250-50-100; 200-100-100 kg/ha for Urea-SP36-KCl, respectively) recommended in Kedurang Ilir, (3) there were 7 packages of fertilizer doses (250-100-100; 200-50-100; 250-75-100; 200-100-75; 200-75-100; 200-100-100; 250-50-100 kg/ha for Urea, SP36, and KCl, respectively) in Seginim.Key Words: paddy soil, fertility, soil test kit

Thermal washer-disinfectors represent a technology that brought about great advantages such as, establishment of protocols, standard operating procedures, reduction in occupational risk of a biological and environmental nature. The efficacy of the cleaning and disinfection obtained by automatic washer disinfectors machines in running programs with different times and temperatures determined by the different official agencies was validated according to recommendations from ISO Standards 15883-1/1999 and HTM2030 (NHS Estates, 1997) for the determining of the Minimum Lethality and DAL both theoretically and through the use with thermocouples. In order to determine the cleaning efficacy, the Soil Test, Biotrace Pro-tect and the Protein Test Kit were used. The procedure to verify the CFU count of viable microorganisms was performed before and after the thermal disinfection. This article shows that the results are in compliance with the ISO and HTM Standards. The validation steps confirmed the high efficacy level of the Medical Washer-Disinfectors. This protocol enabled the evaluation of the procedure based on evidence supported by scientific research, aiming at the support of the Supply Center multi-professional personnel with information and the possibility of developing further research.

<span>Standard laboratory soil testing is deemed to be expensive and time-consuming. Utilizing a soil test kit is considered to be a cost-efficient and time-saving way of soil testing. This project study aims to develop a prototype that detects soil parameters (i.e., soil pH, nitrogen, phosphorus, and potassium) and gives crop and fertilizer recommendations after the soil sample has undergone a soil treatment test kit and its acceptability for possible users. The prototype development primarily used image processing to detect the needed parameters that lead to crop and fertilizer recommendations. In the evaluation of the effectiveness of the prototype, 50 trials were conducted per parameter. All of the said parameters were recorded as highly effective except for nitrogen Low, which is interpreted as effective only. There were 30 possible users invited to assess the acceptability of the prototype. A survey based on the technology acceptance model was administered to the 30 respondents garnering a 4.85 weighted mean interpreted as excellent. The prototype was proven effective and accepted as a device that can detect soil pH and primary macronutrient levels. It gives the appropriate crop and fertilizer recommendations based on the gathered data.</span>

Amirrullah J, Hutapea Y, Ratmini NPS, Prabowo A. 2020. Farmer mentoring in determining fertilization dosage of corn plants (Zea mays L.) using soil test equipment. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 102-108.Balanced fertilization is very important to do in marginal soils. The constraints in the use of marginal soils are physical, chemical and biological soil characteristics which do not support planting growth. Determination of fertilizer dosage for corn commodity in one region can be different depending on the available nutrient content that testing needs to be carried out. This study aimed to mentor farmers in taking appropriate soil samples and determined fertilizer doses according to location specifications and application of fertilizers on target using the Dry Soil Test Kit (Perangkat Uji Tanah Kering). This activity was carried out in Fajar Jaya Village, Ogan Komering Ulu District in February 2019.  The results of the soil analysis of the location used as a demonstration plot derived from the results of low soil fertility analysis with soil acidity at pH 4-5 with acid crystals, moderate P, K and C-organic nutrients were relatively low. The recommended fertilizer is as follows: urea 325 kg/ha given 3 times, one-third the dose, carried out 1 MST, 4 MST and 6 MST; TSP 200 kg/ha; KCl 125 kg/ha; 5,000 kg/ha of compost and 1,000 kg/ha of lime stocked during tillage 1 week before planting. Fertilization application method applied by farmers is not in accordance with the recommendations; consequently, it is necessary to fertilize to increase nutrient content.
