Al - Hawija district lies which undulating terrain. It is run administratively by Kirkuk city. It's total area is about (2430.51) km2, (29%) of Kirkuk to be exact. The planted area is about (737979.84) Donam. That is about (76.0%) of the village's area. It contains (72) territories.The geological formations age return to several ages ago. Especially the Myosin age and the Pleistocene age. These formations are less affected by flexure movements. River sediments covers most of the region's surface. It consists of alluvium, sand, stone, calcareous stone, gypsum and salt. Open spaces belong to the Faris formation and Injana.The region's surface is mostly plain surrounded by Kirkuk's hill height from the east. From the west, it is surrounded by Himreen hill series which is a concaves which fill by covered by sediments like Lower Zab valley, which extends across the northern east of the region to the south west where it meets the village of Tigris river in addition to some seasonal recurrent valleys which rely on rain in winter, the valley of Fadha, Hawija drainages project like Zighetoon valley and Sahil valley.The plaint nature of the region, alongside the gradual stretching of the region play a vital role successfully irrigation projects in the area.The climate is a n important factor in the agricultural production. The region is known for the clarity of summer and winter seasons. In summer, the climate gets warm and rain ceases unlike winter where the climate is just the opposite of summer's climate, rainy and degrees sometimes lower than zero centigrade.The soil in the area are varied according to the factors that help forming it. There is a red soil, brown calcic soil, mid - thicken red soil, calcic soil and furrow soil. These soils vary in thickness and depth.Running across the study area are two rivers, Dijla river and Al - Zab river. The study area also contains irrigation projects which include Al - Hawija irrigation project that supplies (131000) Donam. with water, and Kirkuk irrigation project that supplies a large are of (63936) Donam. The study area also contains many superficially and artecian wells that irrigates (21960) Donam.Natural vegetation inhabits the region as well as some man - made forests that was planted by the government to get the benefit out of its trees. But there is a noticeable decline in the density of the natural and man - made forests due to poor utilization of the agricultural resources.There is a clear variation in the number of the workers in villages or across regions that require bringing workers from neighboring territories. Also, machines are not equally distributed among territories. Al - Hawija territory has (5372) trailers, (249) harvesters, (465) water suppliers and (4314) water pumping machines.For money funds, territories that take governmental loans are only (25%) in number. While most of the farmers fund the planting process from their own money.Land properties are distributed : By distribution contracts (65%). The rest are scattered as (30%) registered lands, (4.7%) by real estate, and around (73%) that property is about (50) Donam. or more.Irrigation processes are many and different. Lands that are irrigated by making flow of water are about (219346) Donam., and by (courtesy) (222934) Donam, lands that rely on rain are about (385020) Donam.Fertilizers used are of two kinds, biological fertilizers which comes from animals' faeces , and chemical fertilizers especially dab and urine, which is provided by agricultural offices and local markets. The amount of fertilizers' usage varies.Crops and animal resources are exposed to different and many diseases like, for instance, wheat charring, in addition to fungous diseases that infect vegetables. As for diseases that infect animals, it include diseases like anthrax, induced abortion, plague, chicken typhoid, bloody diarrhea and Egyptian bronchitis. These diseases infect cows, sheep, goats, buffalos and chicken.Different transportation methods exist in Al - Hawija territory but it is not enough for the territory's needs. Moreover, the badness of the roads due to aging and scarcity of maintenance affected marketing, as well as the deficiency of marketing centers in the territory. The marketing centers that exist are non - working and because of that, farmers are forced to market their crops to the nearest cities.In order to uncover the features of agricultural production on the cadastral units (territories), the study has depended on average relation, standard deviation and correlation coefficient by determining the relationships between variables or factors on territories level, or within a single territory, and on the similarity in the correlation degree between variables.The basic components method (elemental analysis) has been used to measure the characteristics of agricultural investments in the province through factor division matrix. Results show that there are three kinds of agricultural factors (components) that had lost more than (78%) from the total variation of the variables used in the study. These factors (components) are : 1 - First factor (component) : we could call it (intensive agricultural system). It explained (24.78%) of the phenomena under study. This system included (7) territories. There territories represented (33.33%) of the total territories.2 - Second factor (component) : This system explained (13.98%) of the phenomena under study. This system could be named (mixed agricultural system). In this system, it is possible to plant crops heavily and breed different types of animals. (4) territories that represented (19%) of total territories has been included.3 - Third factor (component) : explained (9.66%) of the studied phenomena. It included (3) territories representing (14.3%) of total territories.
