During the regular control of soil fertility in the Rasina District, it was established that the plots of land were distributed across Vertisol, Eutric Cambisol and Fluvisol types of soils, and to a lesser extent on Pseudogley and Ranker. The tested samples had different textures - sandy loam and loam, clay-sandy loam and clay loam, and clay. Plots of land that were of very acidic and acidic reactions were predominant, with medium amounts of humus, very low amounts of available phosphorus, and high amounts of available potassium. High or very high cation absorption capacity was found in about half of the examined fields; a deficient content of exchangeable Ca was recorded in 22% of plots and that of exchangeable Mg in 16% of plots, while an unfavorable Ca/Mg ratio was measured in 44% of plots. The overall sensitivity to acidification was mainly moderate (50.6% of plots) and strong (20.2% of plots). Very high concentrations of mobile Al, which could be toxic to plants, were found in 5 field plots.

Abstrak: Selama proses suksesi, vegetasi merupakan satu dari komponen utama untuk meningkatkan kesuburan tanah. Tujuan penelitian ini adalah untuk menganalisis dan mendeskripsikan peran vegetasi dominan pada karakteristik tanah di lahan bera berumur 15 tahun Kampung Womnowi, Distrik Sidey, Manokwari. Vegetasi dominan ditentukan berdasarkan data indeks nilai penting (INP) analisis vegetasi. Sampel tanah diambil secara komposit pada luasan lahan 1 hektar dari dua kedalaman tanah (0–10 cm dan 10–20 cm). Vegetasi yang mendominasi lahan bera secara berurutan adalah Pometia pinnata, Dracontomelon dao, Octomeles sumatrana, Lansium domesticum, dan Pimelodendron amboinicum. Kehadiran O. sumatrana mengindikasikan lahan bera tanah aluvial, lebih lanjut terbukti karena lahan bera tersebut berdekatan dengan Sungai Womnowi. Karakteristik fisik tanah didominasi oleh fraksi lempung dan unsur makro lebih tinggi pada kedalaman 0–10 cm dibanding kedalaman 10–20 cm. Karakteristik tanah menunjukkan bahwa tanah tergolong masam (pH 5.4–5.6), kadar karbon organik tanah sedang (1.07–3.39%), kadar nitrogen total rendah (0.17–0.53%), kadar fosfor tersedia tergolong tinggi (10.7–22.4 ppm), kapasitas tukar kation (KTK) tergolong tinggi (10.50–20.32 cmol kg-1), kejenuhan basa tergolong sangat tinggi (65.4–66.7%), dan kadar Al3+ and H+ sangat rendah. Secara keseluruhan urutan KTK menunjukkan Ca > Mg > Na > K yang mengonfirmasi tanah aluvial dan pencucian kalium terjadi dengan cepat. Rendahnya kadar kalium dapat dihubungkan dengan penggunaan unsur tersebut untuk pembentukan buah L. domesticum. Selama pemberaan 15 tahun, vegetasi dominan memengaruhi karakteristik tanah.Kata kunci: vegetasi pohon, kesuburan tanah, analisis tanah, aluvial, Papua BaratAbstract: During succesional season vegetation is one of major compound to increase soil fertility. The purpose of this study was to analyzed and description dominant vegetation and their contribution to soil characteristic at fallow land 15 years old Womnowi Village, Sidey District, Manokwari. To determine dominant vegetations we used data important value index (IVI) of vegetation. Two depth of sample soils (0–10 cm dan 10–20 cm) were taken from one hectare area by composite technique. The dominant vegetation on fallow land dominated by Pometia pinnata, Dracontomelon dao, Octomeles sumatrana, Lansium domesticum, and Pimelodendron amboinicum respectively. Presence of O. sumatrana was indicated that the type of aluvial fallow land, further it is proven because the fallow land is close to the Womnowi River. Soil physical characteristic dominated by clay fractions, macronutrient was higher in depth 0-10 cm than 10-20 cm. Characteristic of soil shows acidic soils (pH 5.4–5.6), moderate of soil organic carbon (1.07–3.39%), total of nitrogen was low (0.17–0.53%), high available phosphorus (10.7–22.4 ppm), moderate cation exchange capacity (CEC) (10.50–20.32 cmol kg-1), very high base saturation (65.4–66.7%), and very lows of Al3+ and H+. Overall the order of CEC shows Ca > Mg > Na > K respectively confirmed aluvial soil and fast leached potassium in soil. Low potassium levels are thought be related to the use of the element for fruits formation of L. domesticum. During 15 year fallowed, dominant vegetation had influence to soil characteristic.Key words: tree vegetation, soil fertility, soil analysis, alluvial, West Papua

One of the largest strawberry-producing municipalities of Rio Grande do Sul (RS) is Turuçu, in the South of the State. The strawberry production system adopted by farmers is similar to that used in other regions in Brazil and in the world. The main difference is related to the soil management, which can change the soil chemical properties during the strawberry cycle. This study had the objective of assessing the spatial and temporal distribution of soil fertility parameters using principal component analysis (PCA). Soil sampling was based on topography, dividing the field in three thirds: upper, middle and lower. From each of these thirds, five soil samples were randomly collected in the 0-0.20 m layer, to form a composite sample for each third. Four samples were taken during the strawberry cycle and the following properties were determined: soil organic matter (OM), soil total nitrogen (N), available phosphorus (P) and potassium (K), exchangeable calcium (Ca) and magnesium (Mg), soil pH (pH), cation exchange capacity (CEC) at pH 7.0, soil base (V%) and soil aluminum saturation(m%). No spatial variation was observed for any of the studied soil fertility parameters in the strawberry fields and temporal variation was only detected for available K. Phosphorus and K contents were always high or very high from the beginning of the strawberry cycle, while pH values ranged from very low to very high. Principal component analysis allowed the clustering of all strawberry fields based on variables related to soil acidity and organic matter content.

Most seedlings and saplings of woody plants in the Russian Federation are produced in the open ground in forest nurseries. In order to produce high quality planting material it is necessary to support and preserve soil fertility, which can be obtained by using organic wastes and organic-based fertilizers. Our research is aimed at the assessment of the influence of non-conventional organic fertilizers on fertility of podzols and on the growth rate of seedlings and saplings of woody plants in forest nurseries. Our research shows, that the application of non-conventional organic fertilizers does not result in any accumulation of heavy metal salts in podzols, but optimizes hydro physical and agrochemical properties of the ploughed horizon. The efficiency of non-conventional organic fertilizers depends on their composition, physical and chemical characteristics of the original components, their doses applied and original fertility of soils. A combined application of non-conventional organic fertilizers and sand results in the optimization of practically all soil fertility parameters in middle clay-loam soils, while application of non-conventional organic fertilizers and clay is optimal for application on light soils. The optimal application dose of non-conventional fertilizers depends on soil texture, woody species and the fertilizer composition. An optimal application dose for Norway spruce on a light clay-loam soil is 50-80 tons/ha, and on a middle clay-loam soil is 149-182 tons/ha. It is 50 tons/ha for Scots pine growing on a sandy loam soil, and 100 tons/ha for the same species growing on a sandy soil or a light clay-loam. For Siberian larch growing on a light clay-loam soil the dose of fertilizer applied should be 150 tons/ha. It is recommended to apply composts containing over 50% (by weight) of Category II wastes (substrate) for the amelioration of light soils, and composts containing over 40% (by weight) of Category I wastes (filler) for the amelioration of heavy soils. It would allow for the optimization of soil properties and production of better quality planting material in forest nurseries.

The impact of fertilizers containing macro- and micro-nutrients on seed production of alfalfa under irrigation in Saskatchewan was assessed. Trials were conducted on a Sutherland clay loam at Saskatoon, SK, from 1986 to 1991, and in a commercial field on Asquith sandy loam near Outlook, SK, from 1990 to 1993. Nutrients (primarily combinations of P, K, S) were applied at establishment (in-row with seed, side-banded, or broadcast and incorporated prior to seeding), and/or broadcast on the soil surface each year. Seed yield at both sites was excellent for the region, and application of fertilizer had little or no impact on yield. At sites with adequate initial soil fertility, as indicated by soil testing, alfalfa may not require added fertilizer to maintain high levels of seed production. Key words: Medicago sativa, lucerne

Soil Fertility Status

Soil fertility degradation has become a major problem for agricultural management in Nepal. A detailed soil fertility status of different VDCs of Sunsari district was investigated during 2015 and soil related crop production constraints were identified for proper utilization of agricultural land. Total 131 numbers of geo-referenced (GPS based) composite surface soil samples (0-15 cm) were collected from eleven Village Development Committees of Sunsari District. The sample points were recorded with a differential global position system and mapped using Geographic Information System (GIS). Soils were analyzed for mechanical composition, pH, organic matter, total nitrogen, available phosphorus, potassium and micronutrients like Boron, Zinc, Copper and Iron. About 38.9% soils were found to be silty clay loam, 20.6% were silty clay, 19.1% were clay loam and 21.4% were of other textural classes. Most of the soils were acidic and only few were neutral and slightly alkaline in nature. Soil Organic matter varies from 3.57% to 0.28% with a mean value of 1.53 %. The mean total nitrogen, available phosphorus, potassium was found to be 0.08%, 44.37 kg/ha and 128.04 kg/ha respectively. The mean hot water extractable Boron, DTPA extractable Copper, Zinc and Iron was found to be 0.14, 0.06, 0.15 and 10.71 mg/kg respectively. Thematic maps were prepared for each soil parameters using ArcGis10.1 software and ordinary Kriging interpolation was used in order to predict values for not sampled locations. The fertility maps provide the readymade source of information about soil fertility status and serve as the decision making tool for successful raising and development of crops. It can be concluded from the above study that GPS and GIS based soil fertility maps helps farmers, scientists, planners and students in providing soil test based fertilizer recommendation for intensive and sustainable site specific crop production.Int.

Soil fertility management is important for sustainable crop production. In the bid to boost the agricultural development in Ghana, Krachi Farm Ltd, identified Gyerentor in Kete Krachi within the West District of the Oti Region, formally Volta Region as a potential area for cashew, cowpea, maize and mango production. However, the fertility status of the soil is not known hence the assessment of the suitability of the soil for the above crop production. 30 soil samples were collected randomly from depths of 0-30 and 30-50 cm. Soil sampling points were identified using a GPS device. Following standard methods adopted by Laboratory Analytical Services Department of Soil Research Institute, Ghana,  the collected soil samples were analyzed to find out their texture, pH, organic matter (OM), nitrogen (N), calcium (Ca), magnesium (mg), potassium (K), sodium (Na) and available phosphorus (P). The soil was acidic with the mean value of 4.5 in the topsoil, OM (1.0%), Ca (2.1 me/100 g), mg (0.8 me/100 g), K (0.3 me/100 g) and P (4.6 ppm). The soil texture was sandy loam and sandy clay loam. The fertility of the soil was low in almost all the studied parameters, especially with respect to OM and the NPK levels. Assessment for various land utilization type (LUT) types did not find it suitable for cashew, cowpea, maize and mango especially due to the extremely acidic condition.
