With the vigorous development of the "Purge" campaign, a large amount of land has been vacated, and it is bound to be fully developed in the future with the increase of immigrants.

At present, the agricultural system of the East African colonies is still relatively chaotic, because the colonial population is too scattered, and the crop cultivation is also very different.

The staple foods alone are wheat, rice, and corn, and recently the East African colonies are still trying to introduce millet cultivation in Kenya, which Ernst emphasized, after all, the climate in Kenya, especially the further north it goes, the drier the climate, and millet is a very drought-tolerant crop.

In the past, East Africa was an important production area of millet, and this place is very suitable for millet cultivation, after all, East Africa, as a savannah climate, is most suitable for growing "grass", and millet is still domesticated by dog's tail grass.

This is a food crop, cash crops are even more chaotic, the East African colonies, located in the tropics, basically all tropical plants can be grown, sisal, coffee, rubber, cocoa, all kinds of vegetables and fruits......

If the East African colonies only think about the problem of food and clothing on the mainland, then they can grow anything, but the East African colonies, as an area that Ernst will vigorously develop in the future, must prepare for industrialization after all.

If agriculture wants to pave the way for industrialization, it must first carry out modernization and reform and give full play to its advantages in scale.

To put it bluntly, East Africa's agriculture has to go to the market to fight and earn a lot of real money to accumulate East Africa's original capital.

At present, the best template in Ernst's hands is Argentina, which is a typical country that started out in agriculture, regardless of the problems of subsequent industrialization.

While Argentina has been hugely successful in agriculture alone, East Africa and Argentina share similarities, with the same vast expanse and the same grasslands.

It's just that one is in the temperate and subtropical zone, the other in the tropics, and the land of the East African colonies is only slightly less fertile than the black soil of Argentina.

The precipitation of the two is equally equal, the rainfall in the north of Argentina can reach about 1500mm, the south is only about 600mm, and the East Africa is decreasing from east to west, reaching a peak in the Great Lakes region, with the level of the whole region between 600mm and 1500mm.

This level is not bad in the world, intuitive data: the annual precipitation in the North China Plain is about 600mm, and it is concentrated in July and August.

East Africa, on the other hand, has two rainy seasons, a light rainy season from November to December and a heavy rainy season from April to May.

However, the main reason why the East African colonies advocated the development of agriculture was that the cost of developing agriculture was relatively low, as long as the land was reasonably planned and some production tools were improved, the requirements for technology and personnel were not as high as those of industry.

However, if we want to develop agriculture, taking the "small peasant economy" will definitely be a dead end in this era of the jungle, and it will be more than self-preserving and unable to open up, and will eventually be crushed by the low-cost advantage of large-scale agricultural production.

Capitalist agriculture is characterized by the centralization of land management, and the most prominent of contemporary times are the "Prussian model" and the "American model".

Its essence is to concentrate the land in the hands of a small number of people, operate it in a unified manner, impact the market with the advantage of scale, and occupy the market to obtain huge profits.

The land rights of the East African colonies were directly in the hands of Ernst, so there was no need for top-down reforms, as in Prussia.

But Ernst himself did not abuse blacks, so it was different from American estates.

In this case, Ernst went straight to the model of the big farmstead.

All the land in East Africa was Ernst's private property, the immigrants had no property rights, and were in the nature of agricultural workers on farms.

The way to get paid is naturally to work more and get less.

At present, the East African colonies directly divided several large agricultural areas according to climate and rainfall, and the same crops were cultivated uniformly within the regions.

The Great Lakes region in the west, the Lake Solon region, the Lake North Malawi region, the Lake East Malawi region, and the Central Plateau region, and the southern part of Kenya are dominated by wheat cultivation.

It is determined according to the dietary habits of immigrants and market demand, whether it is Austro-Hungarian immigrants or immigrants from the Far East and North China, they all have pasta habits, and the main market for grain is naturally wheat in Europe.

The three coastal areas in the east, as well as the coastal plains of eastern Kenya, are dominated by rice cultivation.

To the east of the savannah and Great Lakes regions, to the northern highlands, and to the north of Kenya, millet and livestock farming are developed.

Among them, wheat and livestock were the main means of income generation in the East African colonies, in addition to cash crops.

Both of these have deep markets in Europe, and even if Europe can't squeeze in, the Arabs will eat it, after all, most Arabs live on commerce and nomadism, and their own output is too small.

The Far East is not in Ernst's considerations, mainly because the Far East is not rich at present, and it is a purely agricultural production area, and it is poor, and the market competition is still large.

In the past, the most popular crops in East Africa were probably corn and cassava, but Ernst chose wheat for East Africa.

Although corn and cassava are highly productive, they both have certain drawbacks, they need to be processed more expensive than wheat, and the immigrant diet and the European market are still focused on wheat cultivation.

The largest cash crop in the current East African colonies is naturally sisal.

In addition to sisal, Ernst plans to grow five important cash crops: oil crops, rubber plantations, tea plantations, cotton plantations, and coffee plantations.

In addition to these main cash crops, there are also cloves, pyrethrum and other dominant crops.

In the previous life, East Africa was an important cotton producing area in Africa, and all countries in East Africa planted it, so cotton planting was not a problem, and the market was relatively easy to find.

There are more choices of oil crops, peanuts, sesame, soybeans...... and other traditional oil crops can be grown, and there are castor beans and small sunflower seeds in East Africa......

Rubber plantations are mainly planned in coastal areas and around the Great Lakes region, where there is more abundant water.

Tea is mainly cultivated in some mountainous and high-altitude areas, and black tea is directly cultivated in large quantities as in previous lives, and Europeans can't make any difference in drinking it anyway.

These are all crops that need to be produced intensively, and the rest will not be detailed, because the land and climatic conditions of East Africa are simply too superior.

In the past, East Africa also had a flower industry, and a variety of tropical fruits and vegetables, which Ernst of course also coveted, but now the level of technology is not up to it, and it is impossible to achieve large-scale short-term transportation.

Even if it is animal husbandry, Ernst has no way to directly carry out large-scale development in East Africa, and the entire region of East Africa is suitable for the development of animal husbandry, but the problem is that the preservation technology is really stretched.

Unless Ernst initially processes meat in East Africa and makes it into a variety of pickled foods, it will take time.
