dc.description.abstractLack of a systematic and detailed soil survey and land evaluation report for guiding the utilization of the farm necessitated this study.About 1, 097 ha comprising the Northern part of trie farm was covered. It is possible to grow maize, sorghum, soyabeans, fieldbeans, ground- nuts and rice. J<Iaize has a land suitability distribution of 228.5 ha (20,7%) as highly suitable (S1), 225.8 ha (20.4%) as moderately suitable (S2), 534.6 ha (50.6%) as marginally suitable (S5) with 510.5 ha (28.5%) as unsuitable thus not suitable (1;1) and not relevant (NR) combined. fertility problems are very widespi'ead. However low soil moisture retention imposed by coarse texture, compounded with peiā€™iodic droughts is decisive to yields. The land suitability distribution for sorghum is 250.5 ha (22.-7%) as S1, 469.5 ha (42.9%) as 52, 79.1 ha (7.2%) as 35, with 293.5 ha (27.2%) as unsuitable. Soi-ghum has similar limitations to maize but enjoys a higher land suitability area because of its ability to with stand many environmental problems like drought and is more suited to the area than any other crop.Soyabeans have 250.5 ha .7%) as S1, 545.3 ha (51.-5%) as 32, 250.2 ha (21.1%) as 35, and 271.4 ha (24.7%) as unsuitable N1 and NR.The main limitations to soyabean production are fertility and nutrients with suspected low levels of rhizobium due to coarse texture and poor water retention imposed simi 1ariy. A few areas are too wet for soyabeans. There is 250.5 ha (22.7%) rated as 31 for fieldbeans, 266.2 ha (24.5%) as 32, 297.5 (27.2%) as S3, and 283.4 ha (25.8%) as unsuitable.Limitations are similar to anyabeana but adaptation to, shorter growing season lower moisture requirements make beans more suitable,and The land suitability distribution for groundnuts is 305.0 ha (27.7%) as S1,211.5 ha (19.3%) as S2, 230.2 ha (21.1%) as S3 and 350.5 ha (31.9/0 ap unsuitable.Infact Groundnuts have similar tolerances as fieldbeans. coarse textures enhance good pod formation and growth.The land suitability distribution for rice is 90.8 ha (8.3%) as S1, 58*6 ha (5.4%) as S2, 143.1 ha (12.9%) as S3 and 804.7 ha (73.4%) as unsuitable. Excessive drinage due to unfavourable relief and texture give severe limitations to rice production.Land suitability evaluation indicates that good farm management involving application of biological and artificial fertilizers, fertility trials and soil testing, supplementary irrigation, timing planting to soil moisture balance studies (fig. 9) and not statistical crop calendars, selection and breed of suitable crop varieties, crop and grazing rotations and establishment of administrative houses in Hindu and Lugala blocks of land vzill raise farm productivity. and (Table 3) coarse Fertility and low moisture retention (fig. 15) textures (figs. 13 and 14), structurelessness (Plate 11) could be amended by manuring, fire prevention, long fallow periods between rotations, silvicultural and pasture establishment. multi cropping practices The soils with a high water table should be utilized for rice production (fig. 34).
