Factors Of Soil Formation Soil Formation Factors Soil formation is influenced by various factors, namely climate, parent materials, topography, biotic factors (living organisms), and the element of time.   Climate Climate denotes the long-term average weather conditions in a specific location, encompassing factors such as sunlight, temperature, wind, relative humidity, rainfall, and pressure.   Rainfall: […]

Weathering Of Rocks The formation of soil is synonymous with the process known as weathering, which involves the breakdown of rocks into finer particles, ultimately giving rise to soil.   Processes Involved In Rock Weathering Soil formation, or rock weathering, encompasses three primary processes: Physical Process Chemical Process Biological Process   Physical Processes In Rock

Rock A rock is a mineral material found on Earth, often comprising various mineral elements such as silica (which contains silicon and oxygen).   Types Of Rocks Rocks can be categorized into three primary groups based on their formation processes and appearances: Igneous rock Sedimentary rock Metamorphic rock   Formation Of Igneous Rock These rocks

Meaning Of Agricultural Ecology Agricultural Ecology is the exploration of the relationships between crop plants, farm animals, and their surroundings. Derived from the Greek word “Oikos,” meaning home or dwelling place, it encompasses the study of living organisms and their interactions with the environment.   Agricultural Ecology is categorized into: Autecology Synecology   Autecology involves

Cultivation of Cereals   Maize (Zea mays): Maize, commonly known as corn, is a member of the grass family (Gramineae). It produces grains, which serve as a staple food for both humans and livestock. The seed or fruit of maize is called caryopsis. Various varieties include sweet maize, flint maize, dent maize, flour maize, and

Post-planting operations refer to activities conducted after the initial planting phase, aiming to create favorable conditions and ensure proper maintenance for plant growth. These operations encompass various tasks such as thinning, supplying, irrigation, the application of manure and fertilizer, mulching, weeding, harvesting, processing, and storage.   Thinning involves the removal of excess, weak, or poorly

Planting Procedure Planting operations involve the insertion of planting materials, such as cuttings or seeds, into the soil. When seeds are sown, they undergo germination, where the embryo resumes growth under favorable conditions, leading to the emergence of seedlings.   The Process A Seed Undergoes During Planting: Let’s break down the process of seed planting

Before the actual planting process, there are pre-planting operations, such as land clearing, stumping, and farm layout. Land clearing involves removing existing vegetation using tools like cutlasses, hoes, or machinery like bulldozers. Stumping, on the other hand, is the manual or mechanical removal of leftover tree stumps on the farm. Farm layout involves dividing the

Crops refer to plants that are cultivated and grown by humans for various purposes, typically for food, fiber, or other commercial uses. Common crops include grains like wheat, rice, and corn; vegetables like tomatoes, carrots, and potatoes; fruits like apples, oranges, and bananas; and cash crops like cotton and tobacco. The cultivation of crops is

Environmental Factors Impacting Agricultural Production (Crop And Animal Distribution And Production) 1. Climate: Described as the long-term average weather conditions of a location. 2. Factors Of Climate: Comprising rainfall, relative humidity, temperature, light, wind, and pressure.   Each factor exerts its influence on agriculture, evident in the distribution of vegetation and crops across climatic zones.

Land Tenure Systems In Nigeria The ownership of land in Nigeria varies from individual to communal ownership. Under individual ownership, families hold the land and have the right to farm, build, pledge it for money, or sell it. In contrast, communal ownership involves the community, which can be an extended family, village, or town, holding

Land Land represents a natural gift to humanity, constituting the solid portion of the Earth’s surface, encompassing soil and mineral resources where various forms of production, such as agriculture and livestock management, occur.   General Characteristics Of Land Its supply is fixed, and its value increases steadily in response to growing demand. The supply of

Agro-Allied Industries And Their Significance Agro-allied industries, also known as agro-based industries, rely on agriculture for their raw materials to operate effectively. In simpler terms, these industries need a constant supply of agricultural raw materials to manufacture finished products crucial for human and animal consumption.   Illustrations Of Agro-Allied Industries And Their Raw Materials Outlined

Science and technology have played pivotal roles in advancing agriculture not only in Nigeria but also in various nations worldwide. These contributions encompass: Modern Farm Machinery: The advent of contemporary agricultural implements like tractors, plows, planters, harvesters, and shellers, replacing traditional tools such as hoes and cutlasses, owes its existence to the progress in science

Roles of Government in Agricultural Development: The government plays a crucial role in shaping and guiding agricultural activities through its agriculture ministries. Responsibilities include formulating policies and programs, establishing regulations, providing financial support through loans and subsidies, funding research, creating farm settlements, and supplying essential services such as vaccines and quarantine measures.   Establishment of
