ABSTRACTThe reuse of agricultural waste as organic fertilizer has good prospects in increasing land productivity by improving soil biological properties. The aims of this study was to analyze the effect of using ameliorant organic fertilizer application from corn waste to increase the number of soil microbial populations and the growth of maize plants (Zea mays L.). The method was using CRD (Complete Random Design), which consist of 4 treatments with three repetitions: AA (Ameliorant corn organic fertilizer 40 kg/ha), AB (Ameliorant corn organic fertilizer 80 kg/ha), UR (Urea 40 kg/ha), and K (without ameliorant or urea). Calculation of the number of soil microbials colonies was using the plate count method. The results showed that the treatment of ameliorant organic fertilizer had a significant effect on soil microbials population and growth of maize on the parameters of plant height and number of leaves. The treatment of organic fertilizer ameliorant showed no effect on stem diameter.Keywords: Ameliorant; Soil microbes; Organic fertilizer; Zea mays L.

This research was conductedat the experimental field, the Laboratory for Research and Technology Faculty ofAgriculture, University of North Sumatra, Medan from August to November 2016. Thethe design used in this study is a randomized block design factorial using two factors:organic fertilizers (O) with treatment as follows: O0 = Without organic fertilizers,O1 = 100% of doses of organic fertilizer, O2 = 75% of doses of organic fertilizer, O3= 50% of doses of organic fertilizer, O4 = 25% of doses of organic fertilizer.inorganic fertilizer application (A) with treatment as follows: A0 = Withoutinorganic fertilizers, A1 = 100% of doses of inorganic fertilizer recommendations,A2 = 75% of doses of inorganic fertilizer recommendations, A3 = 50% of doses ofinorganic fertilizer recommendations, A4 = 25% of doses of inorganic fertilizerrecommendations. The variables measured were: plant height, shoot dry weight, rootdry weight, dry seed weight. Results showed that 100% Organic fertilizer canincrease growth and yield of corn were higher in soil ultisol. This is indicated bytheir real influence on the growth of plant height ages 8 and 12 WAP, the weight ofdry seed, uptake of N and P, but no significant effect on shoot dry weight, root dryweight and uptake K. Inorganic fertilizer application of 100% can increase growthand yield of corn was higher in soil ultisol. This is indicated by their real influenceon the growth of plant height age 8 WAP, root dry weight and the weight of dry seed,but did not significantly affect plant height age of 12 WAP, shoot dry weight, uptakeof N, P and K.

The soil fertility aspect is characterized by the good biological properties of the soil. One important element of the soil biological properties is the bacterial population present in it. This research was conducted in the laboratory of Microbiology University of Malikussaleh in the May until June 2016. This study aims to determine the number of bacterial populations in soil organic and inorganic so that can be used as an indicator to know the level of soil fertility. Data analysis was done by T-Test that is by comparing the mean of observation parameter to each soil sample. The sampling method used is a composite method, which combines 9 of soil samples taken from 9 sample points on the same plot diagonally both on organic soil and inorganic soil. The results showed the highest bacterial population was found in total organic soil cfu 180500000 and total inorganic soil cfu 62.500.000

Np Fertilizer

Field experiments were carried out at the Department of Agronomy of the Poznań University of Life Sciences to determine the effect of the depth of NP fertilization placement in maize cultivation on the number of plants after emergence. The adopted assumptions were verified based on a six-year field experiment involving four depths of NP fertilizer application (A1—0 cm (broadcast), A2—5 cm (in rows), A3—10 cm (in rows), A4—15 cm (in rows)). The objective of this study was to assess NP fertilizer placement depth, in conjunction with the year, on the number of maize (Zea mays L.) plants after emergence using the additive main effects and multiplicative interaction model. The number of plants after emergence decreased with the depth of NP fertilization in the soil profile, confirming the high dependence of maize on phosphorus and nitrogen availability, as well as greater subsoil loosening during placement. The number of plants after emergence for the experimental NP fertilizer placement depths varied from 7.237 to 8.201 plant m−2 during six years, with an average of 7.687 plant m−2. The 61.51% of variation in the total number of plants after emergence was explained by years differences, 23.21% by differences between NP fertilizer placement depths and 4.68% by NP fertilizer placement depths by years interaction. NP fertilizer placement depth 10 cm (A3) was the most stable (ASV = 1.361) in terms of the number of plants after emergence among the studied NP fertilizer placement depths. Assuming that the maize kernels are placed in the soil at a depth of approx. 5 cm, the fertilizer during starter fertilization should be placed 5 cm to the side and below the kernel. Deeper NP fertilizer application in maize cultivation is not recommended. The condition for the use of agriculture progress, represented by localized fertilization, is the simultaneous recognition of the aspects of yielding physiology of new maize varieties and the assessment of their reaction to deeper seed placement during sowing.

The present experiment was carried out during the 2010 planting season, atthe Teaching and Research Farms, School of Agriculture, Lagos State Polytechnic,Ikorodu, Lagos State with the view to produce liquid fertilizer fromwater hyacinth (Eichhornia crassipies) and compare its effectiveness withpoultry manure on the performance and yield of fluted pumpkin (Telfairiaoccidentalis). Data on number of leaves and length of main vine 2 weeksbefore fertilizer application (BFA) and 3, 6 and 9 weeks after fertilizer applicationÂ (WAFA) and the yield at harvesting were collected and subjected toÂ Analysis of Variance (ANOVA) and means compared using Least SignificanceÂ Difference (LSD). The results showed that at 3 WAFA, water hyacinth had theÂ highest number of leaves (245) and longest length main vine (2.04 cm) and inÂ terms of yield at harvesting, water hyacinth (16.08 kg) was not significantlyÂ different (P>0.05) compared to poultry manure (18.13 kg) application. FromÂ the study it can be concluded that water hyacinth liquid fertilizer can be utilizedÂ as good source of organic fertilizer for the growth of fluted pumpkin andÂ thus serve as veritable means of curbing the menace of water hyacinth onÂ our water ways.

Agricultural ecosystems are one of the largest global contributors to nitrate (NO3−) contamination of surface- and groundwater through fertilizer application. Improved fertilizer practices are needed to manage crop nutrient supply in corn (Zea mays L.) while minimizing impacts to clean water reserves. The goal of this study was to compare current nitrogen (N) fertilizer practices (urea at planting) with “packages” of improved management practices (a combination of right timing and product) that farmers potentially use. We conducted measurements in a continuous corn system from November 2015 to May 2017 at a large field scale (four 4 ha plots). Nitrate concentration was measured below the root zone and drainage estimated using a soil water budget approach in which evapotranspiration was measured using the eddy covariance method. The objective was to compare NO3−-N leaching from fields receiving urea vs. urea + combination of nitrification and urease inhibitors (NUI) fertilizer applications at planting, urea–ammonium nitrate (UAN) vs. UAN + NUI applied at sidedress, and a combination of these practices: urea + NUI at planting vs. UAN at sidedress. Drainage was only significant in the non-growing season. Neither fertilizer products applied with NUI at planting or sidedress proved to significantly reduce NO3−-N leaching. The combination of delaying fertilization to sidedress and applying UAN significantly reduced the soil water NO3−-N concentration compared with urea + NUI at planting (mean of 5.2 vs. 6.7 mg L−1) but only in 2015–2016. Based on these results, applying UAN at sidedress is recommended, although additional study years are needed to confirm those results.
