Land evaluation is one of the most important tools for integrated land use management for sustainable agricultural and land use planning. The aim of this study is to evaluate the land suitability for current land use in akkar plain- Tartous Governorate. Depending on the elevation and land use, nine soil profiles representing the main physiographic units have been chosen. Soil samples were collected for conducting some chemical and physical analyses such as: soil texture (sand%, silt% and clay%), the content of organic matter OM, Cation Exchange Capacity CEC (cmol(+)/kg -1clay). The results of the soil analysis showed that the soil texture was Clay, and the pH values were between 7.13-8.5. Furthermore, The cation exchange capacity were ranging from (12-33) (cmol(+)/kg -1clay). Results of land evaluation showed that the limiting factors either fertility factors such as high pH in the villages of Beit-kamouna, Majdaloun-albaher and Dier-hbash, or physical factors such as shallowness depth of soil. The study concluded that the suitability class ranged from S2 to N2, which emphasis the importance of reconsidering the type of land use in the study area.

Tijayan Village is located in Manisrenggo District, Klaten Regency, which has an area of agricultural land in the form of rice fields which is 105.80 ha of 155.3 ha of the village area. The extent of agricultural land in Tijayan Village needs to be maintained to increase agricultural products ranging from rice, secondary crops, and horticulture commodities. The researcher found a lack of information about soil maintenance in Tijayan Village. Therefore, the researcher conducted this research to determine and study the soil fertility and soil management efforts based on the limiting factors of fertility in Tijayan Village. In addition, soil fertility assessment is based on a desk study, detailed survey, soil analysis, making fertility distribution maps, and descriptive analysis. Determination of soil fertility status based on Soil Research Guidelines published by Soil Research Center, Bogor Indonesia, with parameters of cation exchange capacity, base saturation, total phosphorus, total potassium, and C- organic. Map made by using the ArcGIS 10.4 application. The fertility of Tijayan Village is categorized as low soil fertility class. The limiting factors for soil fertility are soil cation exchange capacity 3.47 me/ 100 g until 12.33 me/100g, total potassium < 10 mg/100g, and C- organic 1.213% - 2.286% . Consequently, management needs to be done by adding organic matter to the soil, fertilizing organically or inorganically, and the principle of healthy plant cultivation for rice fields.

A survey was carried out to investigate the acidification due to acid changes of different land use patterns. The results showed that soil acidification happened in the arable land and forest land in topsoil of 0~10 cm depth, 0.42 and 0.24 pH unit-1 lower than that of in 80~100 cm depth. The lowest cation exchange capacity (CEC) (11.99 cmol·kg-1) was got in the topsoil of paddy soil, while the highest one was in the topsoil of grassland with 19.26 cmol·kg-1. A catastrophe point of cation exchange capacity of soils was found between 20~30 cm except for orchard soil. Organic matter in forest soil decreased sharply by 2.21% in 0~10 cm as compared with that of in 80~100 cm and little decrease about 0.97% was found in the orchard soil. The pH and magnetic susceptibility showed similar variation trend. Multiple linear regression analysis showed that there was a negative relationship between pH and low magnetic susceptibility. Our results also showed that the free iron, low magnetic susceptibility and amorphous ferric oxide were the main factors on the changes of pH in the arable land and forest soil, grassland and paddy soil, and the orchard soil, respectively.

The great potential in coastal sandy lands is followed by various problems and limiting factors that cause the acceleration of land use for agricultural purpose run very slowly. To overcome these limiting factors, appropriate modification and implementation of innovation is needed, namely the providing of soil conditioning materials, such as organic matter. One source of organic material that is still very rarely used, affordable, easy and cheap and simple in its application is the waste of coconut powder and human waste which we call biococotin. Providing of biococotin in coastal sandy lands decreases basic pH near neutral, increasing levels of N, P, K, C-Organic and cation exchange capacity has decreased from 7.20 to 6.40%. N levels increased from 0.021% to 0.17%, P-available increased from 2.52 ppm to 20.13 ppm, K levels increased from 2.52 cmol (+) to 9.35 cmol (+) and CEC increased from 4, 04 cmol (+) / kg becomes 7.07 cmol (+) / kg. The best growth parameters (plant height, number of leaves, longest leaf length and longest leaf width) are shown by treatment 2 which is half the dose of NPK and biococotin. The best average planting weight and yield per ha is shown by treatment 2, which is half the dose of NPK and biococotin, which is 44.03 grams / plant and 26.41 tons / ha bicocotin. Keywords : Biococotin, Coastal area, Cocopeat

Herbicide Treatments

Soil microalgae live on small communities that change structure depending on many factors. Some of these factors include soil pH, agricultural practices as well as pesticide and herbicide treatments.  The size and activity of these soil microbial communities is an indicator of health, quality and fertility necessary for sustainable agriculture.  Methods:A commercial proprietary suspension of microalgae GOgreen®was applied at different concentrations through a center pivot irrigation system to a crop of cultivated corn (Zea mays) during six months.  Experimental plots of 0.5 acres each were planted in four rows. Corn (34,000 plants/acre) was planted in May and harvested in November allowing each plot to be studied for 6 months. In addition, one plot was planted for a second year to study the effects of consecutive planting and harvesting on algae populations in the soil. Soil samples were collected at a depth of 6 inches. Microalgae species identification was based on morphological criteria. Soil analysis included organic matter content (OM), pH and cation exchange capacity (CEC).Results:Treatment with GOgreen®has significant and measurable positive effects on soil OM content, CEC, pH and microalgae species diversity.Conclusions:  It was demonstrated through this study that GOgreen®increased diatom numbers and microalgae species diversity showing a restorative effect on soil quality after herbicide treatment in heavily farmed soil. Additionally, GOgreen®lowers the pH in soils with a pH higher than 7.0 emerging as an economical alternative that is safe for humans and the environment.

The Relationship

Data on soil texture, lime, gypsum, cation-exchange capacity, salinity, alkalinity, hydraulic conductivity and their interrelations and variations are discussed. An equation expresses the relationship between exchangeable Na and cations soluble in 1: 1 extracts. Special attention is paid to whether alkalization and structure deterioration will occur during reclamation. Gypsum contents seem to be adequate for replacement of Na by Ca during leaching but temporary decrease in permeability in early stages of leaching may occur due to retarded exchange reactions caused by the nature of the clay minerals.

Peanut is a plant that has an important role in land and has a high selling value. Therefore it is necessary to take appropriate steps to develop peanut cultivation in the Panasen Sub-watershed by knowing the level of land suitability. The problems faced by the community are 1) lack of interest in the community to plant peanuts, 2) land-use change from agricultural land to lodging land 3) land evaluation has never been carried out for peanut plants in the area. The study used a land unit approach supported by soil analysis, plant growth requirements, and matching. The results showed that the research area was classified as suitable for peanut plants with a suitability class S2 (quite suitable) with a total of 4 land units, namely S2rfns (945.41 ha), S2sn (1675.15 ha), S2srn (938.05 ha), S2sn (13.45 ha) and class suitability of S3 (according to marginal) with 2 land units, namely S3s (12.95 ha), S3s (15.67 ha). The limiting factors for suitability class S2 are root media (r), nutrient retention (f), nutrient availability (n) and terrain (s). The limiting factor for suitability class S3 is the field (s). The limiting factor for N1 land suitability is nutrient availability (n), root media (r) and terrain (s). The limiting factors for conformity class N2 are the field (s) and the rooting medium (r).

Ph Curve

Controlling soil pH is important to ensure good crop yield. This study was conducted to determine whether the accuracy of the existing Shoemaker-McLean-Pratt (SMP) pH-buffer method could be improved by using the pH-dependent cation exchange capacity curve (CECpd). Soil pH, SMP and CECpd measurements were performed on 18 acid surface horizon soil samples, with textures from sandy loam to clay loam. These soils were incubated with three levels of calcium carbonate for 12 wk, after which the soil pH and the effective cation exchange capacity (CECe) were measured. The correlation coefficient (R2) for the CECpd and CECe curves was 0.96. The main factor affecting the slope of the curves is the soil organic matter content. The increase of CECe in the soil was also found to be directly proportional to the amount of lime applied, regardless of the type of soil. By using the slope of the Qv versus pH curve for each soil and the relationship between CECe and lime application, we were able to determine the lime required to raise the soil pH in water to 6.5. As an alternative to the current practice of using the SMP buffer, we propose that it should be possible to estimate the pH-dependent CEC curve from measurable soil properties (e.g., organic matter) and to estimate the lime requirement as the difference in CECpd between the existing and desired pH values. Once the slope of the Qv/pH relationship has been determined or estimated for a soil, the only measurement necessary for calculating lime requirement in subsequent years would be the soil pH. The proposed method would provide lime requirement estimates while decreasing the annual cost of soil analysis.
