Agroforestry is defined as a system that integrates agriculture and forestry by combining the production of arable farming (or crop farming) and forest tree crops on the same piece of land at the same time. For example, crops like maize, yam, and cassava are intercropped with trees like timber, walnuts, pear, chestnut, apple, cherries, apicots, peaches and almonds.
Agroforestry integrates trees and shrubs with crops (and even livestock,) combining forestry and agriculture in order to create biodiversity, while also improving the farmer's income.
Please read on ranching in agriculture here.
A term that describes agroforestry is the Taungya Farming
Taungya farming is an agroforestry system whereby a farmer cultivates agricultural crops alongside young forest trees on the same plot of land. This system of farming benefits the farmer by providing him with food (through food crops) and income (through forest trees)
Agricplease read on arable farming (monocropping) here.
It improves the farmer's skill and knowledge on forestry and diversified agriculture. Please read on forest management and importance of forest in agriculture here.
Available fertile land is fully used for the cultivation of crops.
The cost of tree establishment will be reduced.
It provides the farmer with both income and food.
It give landless farmer and opportunity to cultivate crops. Please read on the branches of agriculture here.
It lowers the cost of agrochemicals like pesticides and fertilizers due to natural soil enrichment from trees and leguminous crops.
It checks and prevents erosion.
It improves humus and overall soil fertility, alongside soil water retention. Please read on clay soil explained with its characteristics here.
It creates employment opportunities in rural communities.
It helps reduce climate change by absorbing carbon(IV)oxide from the atmosphere, while also introducing oxygen into it.
There is competition between food crops and forest trees for resources like light, space, water and nutrients.
Only annual and biennial crops are cultivated in the forest reserve. Please read on the differences between plants and crops here.
Mechanized farming cannot be practiced.
Forest fires can destroy crops.
It may lead to loss of soil fertility over time. Please read on loamy soil and its characteristics here.
It may iincrease the land's susceptibility to accelerated erosion.
Forest trees can harbor pathogens and pests that may spread to agricultural crops.
The farmers may become exploited from issues arising from land tenure system. Please read on land as a factor of production in agriculture here.
The farmers may lack the technical knowhow on the knowledge and usage of appropriate tools, and this can limit overall yield.
Taungya farming may not support the cultivation of certain crops, e g cocoa and rubber; and rearing of certain animals.

Amazing facts in Agricultural Science
Cows technically have one stomach, not four. However, a cow's stomach has four compartments. These are: rumen, reticulum, omasum and abomasum
Peanuts are legumes and not nuts
Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments
Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them
Cows have got the ability to walk up stairs, but not down stairs
A group of cows is called a team, drove or herd.
People just prefer to call them herd
Notable points in Agricultural Science
Below are characteristics of gymnosperms:
Their seeds have cones that protect them.
Sepals and petals aren't present in their cones.
Stigma and style are absent.
They do not produce fruits. Only seeds are formed.
Companion cells are absent.
Sporophyll form the cones.
Anther and filament are absent.
The ovules are not present in the ovary.
Gymnosperms do not possess flowers.
Please read on the anatomical differences between gymnosperms and angiosperms here
The flower is the reproductive organ in plants' sexual reproduction. In order to achieve a successful sexual propagation or reproduction in plants, the floral parts of the flower are utilized.
The floral parts of a flower consists of the followings:
Sepals
Petals
Stamen
Carpel
The stamen is male portion of a plant. It consists of the anther and filament.
The carpel (or pistil) is the female portion of the plant. It consists of the stigma, style and ovary.
An organism will be considered a pest if it does one of the followings:
Attack crops and eat its seeds, roots, stem, leaves and flowers. Examples are locust and grasshoppers.
Cause damage to stored food, fruits or other agricultural produce. Some may even urinate or deaficate on these products. Examples are rodents, cockroaches and mice.
Attack and kill farm animals like goats, sheep and cattle. Examples are foxes, wild cats and snakes.
Act as disease vectors. A vector is an organism that carries parasite and other disease causing organisms, without being affected; but when they introduce the parasites into their host, such host becomes infected with disease. Examples of vectors are rodents and mosquitoes.
Below are the classification of crops based on their uses:
Oil crops
Vegetable crops
Latex crops
Drug and Medicinal crops
Beverage crops
Fibre crops
Fruit crops
Root and Tubers
Legumes
Spices
Cereals
All crops are plants but not all plants are crops. Below are some instances:
Weeds are considered as plants, not crops.
Parasitic plants are not necessarily crops. Examples of parasitic plants include mistletoe, corpse flower and striga.
Carnivorous or insectivorous plants are not necessarily crops. Examples are sundew, venus flytrap and pitcher plant. The image below shows a carnivorous plant (venus flytrap).
Meanwhile, always understand that all crops are plants, and they are grown for food, money or something beneficial.
