Slide1
LAND use, MANAGEMENT, and its effects on fertility
Slide2Land Use
Humans have been utilizing the land since the beginning of time, building settlements where there was access to water and fertile soils. Over time developments have been made in order to properly manage land use. Agriculture has been the driving force behind land use, but today there are more needs than just agriculture. Needs such as municipal, transportation, energy, recreation, and waste management.
Slide3Land Use/Management
In order to use land we must know what terrain we are dealing with.
Land Cover
– refers to the landscape. Is it forest, is it grassland, is it open water, is it mountainous, etc.
Land Use
– shows how people use the landscape. Agriculture, municipal, mixed use, infrastructure, etc.
Land cover data and mapping are major tools for land developers.
Slide4Land Uses
Here are some of the General Categories for Land Use:
Agriculture
Residential
Commercial
Institutional
Industrial
Transportation
Recreational
Governmental
Utility
Open Space
Note: Each category will have subcategories
Slide5Zoning
Urban Land Use Planning is crucial to help minimize the degradation of air, water, land, biodiversity, and natural resources.
Zoning
is the most widely used approach. It designates certain parcels of land for certain use.
What is Zoning?
Philadelphia Parks and Open Space
Slide6Land Uses
All categories of Land
U
se can contribute to erosion, pollution, and fertility problems; even open space land use if not managed correctly.
Maintaining and managing the factors of soil/land fertility need to be considered for all types of Land Use.
Slide7What are the Factors of Soil/Land Fertility?
soil
organic matter (including microbial biomass)
soil texture
soil depth
nutrient content
storage capacity (absorption capacity)
soil reaction
absence of toxic
elements
Vermicomposting (Soil Biology and Microbiology)
Slide8Agriculture
Agricultural use is the only Land Use that utilizes techniques to manage soil fertility.
Agriculture uses large quantities of fertilizers and pesticides.
Erosion becomes more prominent with modifying landscapes to accommodate crops. Erosion leads to loss of nutrients for soil fertility and causes water pollution due to the accumulation of sediments.
Use of
cover crops
and
conservation
tilling
help to maintain and improve soil fertility.
Cover Cropping and Conservation Tillage
Slide9Other Land Uses
Urban development typically is not focused on having fertile soil. However, it contributes drastically to the reduction of soil fertility.
