Land evaluation is an assessment of the potential of land resources. The results of land evaluation will provide information on the best use of it which will lead to expected value of production. This study aimed to determine the level of suitability of the cocoa plantations in Bantaeng Regency using the FAO and Sys methods; make a map of the actual and potential land suitability. The results of the analysis showed that the actual cocoa land suitability of the FAO method was presented in distribution points according to marginal (S3rn) with limiting factor of rooting media and nutrients availability. While the actual land suitability analysis of the cocoa Sys method was not suitable (N1cSf) with climate limiting factors, the soil physical properties and soil fertility. Based on the limiting factors the physical properties of the two methods, there were similarities in effective depth (FAO) and soil depth (Sys), S3 parameters according to FAO and N1 according to Sys. The limiting factor for the soil chemical properties of the two methods was also the same, the availability of S3 (FAO) nutrients, while the (Sys) method was the soil fertility N1.

Weathering of rocks is the crucial first step in making vineyards possible. For where the debris produced by weathering—the sediment we met in Chapter 5—becomes mixed with moist humus, it will be capable of supporting higher plant life. And thus we have soil, that fundamental prerequisite of all vineyards, indeed of the world’s agriculture. So how does this essential process of weathering come about? Any bare rock at the Earth’s surface is continually under attack. Be it a rocky cliff, a stone cathedral, or a tombstone, there will always be chemical weathering—chemical reactions between its surface and the atmosphere A freshly hewn block of building stone may look indestructible, but before long it will start to look a bit discolored and its surface a little crumbly. We are all familiar with an analogy of this: a fresh surface of iron or steel reacting with moisture and oxygen in the air to form the coating we call rust. In his “Guide to the Lakes” of England, William Wordsworth put the effects of weathering far more picturesquely: “elementary particles crumbling down, over-spread with an intermixture of colors, like the compound hues of a dove’s neck.” A weathered rock is one that is being weakened, broken down. The rock fragments themselves are further attacked, which is why stones in a vineyard often show an outer coating of discolored material, sometimes referred to as a weathering rind (Figure 9.1; see Plate 22). If the stone is broken open, it may show multiple zones of differing colors paralleling the outer surface of the fragment and enclosing a core of fresh rock. Iron minerals soon weather to a powdery combination of hematite, goethite, and limonite, and the rock takes on a reddish-brown, rusty-looking color. The great example of such weathering in viticulture is the celebrated terra rossa, but the rosy soils in parts of Western Australia and places further east such as McLaren Vale and the Barossa Valley are also due to iron minerals. Several Australian wines take their names from this “ironstone.”

This study compares the performance of three land evaluation methods, viz., FAO Simple Limitation, Storie Index and InfoCrop simulation model, for assessing the suitability of cotton soils (represented by nine different soil series) of Nagpur district, Maharashtra, India. The Simple Limitation method categorised Wardha, Parseoni and Bhugaon soil series as moderately suitable and the remaining are marginally suitable for rainfed cotton. The values of Land Index, determined by the Storie method, ranged from 20.3 for Manori series to 55.3 for Bhugaon series. Rainfed cotton yields, simulated by InfoCrop model ranged from 761 kg ha-1 in Manori series to 2881 kg ha-1 in Katol series. The Relative Yield Index (RYI) ranged from 0.154 for Manori series to 0.585 for Katol series. Kinhala, Katol and Takali soil series, classified as marginally suitable by the Simple Limitation method, were upgraded as moderately suitable by Sys parametric method. The results of InfoCrop model justified this up-gradation with the high values of RYI that ranged from 0.574 to 0.585. Soils of Manori and Hatodi series are not suitable for cultivating rainfed cotton. Soil depth, hydraulic conductivity and plant available water in the soil were critical factors governing cotton yield and ranking of soils for their suitability.

Abstract Camelina [Camelina sativa (L.) Crantz], a recently rediscovered oil crop is becoming of interest to both industry and farmers due to its relatively wide use. The amount of camelina seed production is / will be influenced both by the demand from the industry and by the suitable conditions that allow its profitable cultivation. A preliminary insight on optimal part of the used arable land in Slovakia suitable for growing this crop was based on available information on the environmental requirements of camelina and the system of land evaluation units of agricultural soils. These data have been acquired from database managed and continuously updated by National Agriculture and Food Centre – Soil Science and Conservation Research Institute Bratislava. From this database information concerning the climatic region, slope, soil texture, soil depth, and skeleton content were used. The obtained results show that approximately 27% of the acreage of utilised arable land has optimal quality for spring camelina cultivation in Slovakia. If camelina will be used for the production of various biobased materials, on a smaller scale (several thousand hectares) it is possible to grow this crop without a significant restriction of the cultivation of other crops, especially those intended for food and feed production. In case of camelina utilisation as a feedstock for conventional biofuels production, it is necessary to take into account its competitiveness compared to oilseed rape, which is currently the main raw material for FAME (fatty acid methyl ester) production, both in terms of profitability of cultivation and CO2 emissions per tonne of oilseed yield.

The development of the agricultural sector is considered the backbone of sustainable development in Egypt. While the developing countries of the world face many challenges regarding food security due to rapid population growth and limited agricultural resources, this study aimed to assess the soils of Sidi Barrani and Salloum using multivariate analysis to determine the land capability and crop suitability for potential alternative crop uses, based on using principal component analysis (PCA), agglomerative hierarchical cluster analysis (AHC) and the Almagra model of MicroLEIS. In total, 24 soil profiles were dug, to represent the geomorphic units of the study area, and the soil physicochemical parameters were analyzed in laboratory. The land capability assessment was classified into five significant classes (C1 to C5) based on AHC and PCA analyses. The class C1 represents the highest capable class while C5 is assigned to lowest class. The results indicated that about 7% of the total area was classified as highly capable land (C1), which is area characterized by high concentrations of macronutrients (N, P, K) and low soil salinity value. However, about 52% of the total area was assigned to moderately high class (C2), and 29% was allocated in moderate class (C3), whilst the remaining area (12%) was classified as the low (C4) and not capable (C5) classes, due to soil limitations such as shallow soil depth, high salinity, and increased erosion susceptibility. Moreover, the results of the Almagra soil suitability model for ten crops were described into four suitability classes, while about 37% of the study area was allocated in the highly suitable class (S2) for wheat, olive, alfalfa, sugar beet and fig. Furthermore, 13% of the area was categorized as highly suitable soil (S2) for citrus and peach. On the other hand, about 50% of the total area was assigned to the marginal class (S4) for most of the selected crops. Hence, the use of multivariate analysis, mapping land capability and modeling the soil suitability for diverse crops help the decision makers with regard to potential agricultural development.

Land Evaluation

Az 1990-es években újraindult, több egyetem és kutatóintézet részvételével folyó hazai földminősítési kutatások két évtizeden átívelő munkálatai révén kidolgozásra került az ún. D- e -Meter földminősítési rendszer. A földminőségre ható talajtani és klimatikus tényezők parametrizálását nagy mintaszámú, idősoros növénytermesztési és talajvizsgálati adatok alapján, valamint a klimatikus agrárpotenciált tükröző nagytájak és Magyarország agroökológiai fajspecifikus paramétereire (Szász , 1999, 2002) támaszkodva végeztük. A vizsgálati adatbázist az 1980-as években az Agrokémiai Információs és Irányítási Rendszer keretei között begyűjtött adatok (mintegy 80.000 parcella öt évre szóló adatai), valamint részletes talajtérképeket is tartalmazó mintaterületi adatbázisok jelentették. A D- e -Meter projekt földminősítési kutatási eredményeit összegezve elmondható, hogy kialakításra került egy új, környezeti elemeket alapul vevő földminősítési rendszer, ami: – statisztikai vizsgálatokon nyugszik és kvantitatív módon határozza meg a termőhelyek produkciós potenciálját; – a művelésben álló, vagy művelésbe vonható hazai talajféleségekre, ill. valamennyi szántó termőhelyre érvényes; – a főbb gazdasági növények, illetve növénycsoportok szerinti értékelést is ad; – tartalmazza a klimatikus hatásokból eredő, talajtani és földtani tényezőkön keresztül érvényesülő termékenységcsökkenés és termelési kockázat (aszály, belvíz) kifejezésének lehetőségét; – a produkciós viszonyokat különböző művelési intenzitási szinteken is jellemzi; – a földminőségről mezőgazdasági parcella szinten is megbízható információt nyújt. A D- e -Meter földminősítési módszer kidolgozásával és annak informatikai rendszerbe integrálásával megteremtődtek az alapok a sokat bírált aranykoronás földértékelési rendszer kiváltásának, valamint a környezetgazdálkodás magasabb szintű tervezésének is.
