Farm development using aerial photointerpretation in Ruvu River Valley, Ragamoyo, Tanzania, East Africa B.P.Mdamu & M.A.Pazi Ministry of water energy & minerals project preparation division, Tanzania ABSTRACT: Soil survey study using romote sensing techniques is important in agricultural development planning. Aerial photography has to be enhanced in acquiring accurate soil and other natural resources maps. Aerial photographs were used to delineate soil bounda ries of a 10,000 acre farm at Maktirunge Village in Bagamoyo district. The virgin wood land project area lies approximately 6.5 and 6.75» South and between 38*5 and 39«0 East. Rainfall is bimodal with intervening short dry season. Landscape mapping was phy- siographically done using 1:50,000 aerial photographs taken in 1966. Landforms were almost flat alluvial plain and undulating coastal plain» The soils originated from sedi mentary and metamorphic rocks with alluvium deposits. After collecting and analysing a total of 206 soil samples, a soil map was compiled at a scale of 1:10,000. Analytical data revealed that soils were non-saline with reasonable amounts of available phosphorus, nitrogen and organic matter. Proper soil management practices are essential in improving the soil conditions. 1. INTRODUCTION 1.1. Purpose of the study Agriculture is the backbone of Tanzania's economy. In 1982 the government outlined a national agricultural policy which was aimed at foods self sufficiency in the co untry. In implementing the policy a nu mber of firms government and private, sta rted to open up newland for development. One of the areas opened up being Makurunge Farm in Bagamoyo district. However, in order to be precise in land planning and soil fertility management soils had to be tested scientificaly and evaluated. The Project Preparation Divi sion in the Ministry of Water, Energy and Minerals was requested to carry out a Semi detailed soil survey of 10,000 acres and make recommendations on the soils potenti- lity and fertility status. The field soil survey was started on 6th August, 1984 and ended up on 4 th September, 1984. A total of 52 soil profiles were dug and described and 206 soil samples collected for Chemical analyses. Therefore this paper is a result of the conducted soil survey and the soil analyses conducted to determine the soils physical and chemical characteristics and their suitability to agricultural purposes. 1.2. Site Location The Makurunge farm is in Bagamoyo district l6.0km. South West of Bagamoyo township. It is bordored in the East by Ruvu riveTr, in the south by Msumbiji river, in the No rth and North West by the Old Makurunge Village. It extends between latitudes 6.5 south and 6.75 South, and between lo ngitudes 38.5° Bast and 39.00° East. The area also lies within the coastal belt of the Indian ocean and its altitude is within 200 meters above sea level. Most of the area is a virgin woodland w r i th bush. It consists of two landscapes namely:- 1. The coastal plain area and 2. The Alluvial flood plain. In general the entire area has a more or less low uniform relief with drainage va lleys. 1.3« Climate This area has two rain seasons. The heavy- long rains begin in March and end in June whereas the short rains normally start in October and December. The rains are cau sed by the movement of the Inter Tropical Convergence zone (ITCZ) over the area. The convergence zone moves across the area in October when the belt is shifting from the Northen hemisphere to the South and some time in January when the belt moves from the southern hemisphere to the North. The duration of the short and long rains de pends upon the fluctuations of the belt over the area. The climatological data obtained from Bagamoyo town meteorological station which is situated l6.0km East of the Makurunge Farm and fo\ind within the same elevation of the project area, indicates that the mean annual rainfall is between 800 and 1000mm. The highest rainfall is received in April with a precipitation of about 286.9mm. A pronounced dry season starts in June to September. There is a short dry season from January to Mid March. The average mean tempre is 24.5 C. (figure 2). 1.4 Geology of the area The geological substratum of the region is underlain by rocks of the kainozoic system which is stratigraphically made up of se dimentary and metamorphic rocks. The flood plain valley is dominated by recent alluv ial material deposited by the river during floods. Which consist of silt clay and raregravels. The coastal plain area is made up of sedimentary and metamorphic rocks with interbedded sandy clays and scattered gravels; calcareous materials are found in some localities at deeper depths (l00-150cm) e.g pits number 4-13» 25-29 (Appendix 1).
