2. WHAT IS SOIL MANAGEMENT?
Soil management is the application of operations,
practices, and treatments to protect soil and
enhance its performance (such as soil fertility or
soil mechanics). It includes soil conservation, soil
amendment, and optimal soil health
3. Physical characteristics of soils
Physical properties of soil include color,
texture, structure, porosity, density,
consistence, temperature, and air.
Colors of soils vary widely and indicate
such important properties as organic
matter, water, and redox conditions
4. Chemical characteristics of soils
They occur naturally in the soil to some
extent and can be supplemented with
fertilizers, manure and compost. Legumes
can bind nitrogen. The macro-elements are
calcium (Ca), magnesium (Mg), potassium
(K), Sulphur (S), phosphate (P), nitrogen
(N), sodium (Na).
5. CON’
The chemical soil fertility is largely
determined by the presence of macro-
elements, the presence of micro-
elements or trace elements, the acidity
or pH, the salt content or EC and the
cation-exchange capacity or CEC.
6. State The Methodologies
Indicators of soil properties can be
physical, chemical or biological. Ideal
indicators are simple and inexpensive
to obtain and interpret.
7. PROCEDURES THAT YOU WOULD UNDERTAKE TO
DETERMINE THE PH OF A PARTICULAR SOIL
It is measure of the concentration of
free hydrogen ion (H+) that are in the
soil. Soil pH can be measured in water
or a weak calcium chloride solution .
The pH range is from 0-14 with value
of value of 7 being neutral
8. Outline the procedures that you would undertake
to determine the pH of a particular soil.
It is measure of the concentration of
free hydrogen ion (H+) that are in the
soil. Soil pH can be measured in water a
weak calcium chloride solution . The pH
range is from 0-14 with value of value of 7
being neutral
9. Evaluate the need for application of Ameliorants where
necessary and tools and equipment's that are used in the
process
The important for ameliorants: Ameliorants is defined
as something that improves the condition of someone or
something ameliorants can also be defined as an chemical
that is applied to improve the quality of the soil and
thereby improve plant growth. Fertilizers play an
important role in the development of crops by providing
required nutrients . They may Also improve the quality of
crops . Fertilizers also help improve yield , which is one of
the most crucial requirements for bridging the gap
between an ever – increasing human population and
limited arable land
11. Assess the need for OHS standards when
undertaking soil management activities
Occupational health and safety (OHS) relates to
health, safety, and welfare issues in the
workplace. OHS includes the laws, standards, and
programs that are aimed at making the workplace
better for workers, along with co-workers, family
members, customers, and other stakeholders.
12. Soil management activities will include
The use of
largesmall
machines, tools and
equipment's.
Handling of
chemicals.
These can result in
life and death
fatalities.
These activities will
interduces risks and
potential hazards to
hum soever, will
carry out these
activities
13. This is when the OHS
standards fall in place.
These standards will
include: the use of
(PPE),doing risks
assessments to minimize
hazards etc
14. Why these practices should be
carried out
In order to control workplace hazards and eliminate
or reduce the risks. Steps that can be carried out
to reduce these risks are:
identify the hazard by carrying out a workplacework
area risk assessment
determine how employees might be at risk
evaluate the risks
record and review hazards at least annually, or earlier
if something changes
15. Check equipment’s before use
The purpose of an inspection is to identify
whether work equipment can be operated,
adjusted and maintained safely – with any
deterioration detected and
remedied before it results in a health and
safety risk. ... The need for inspection and
inspection frequencies should be
determined through risk assessment
16. Why is this done?
Safety Inspections ensure that all equipment is
safe before use. Of course, the primary purpose
of safety is the well-being of employees, but
there are also compelling business reasons for
using equipment inspections to increase safety
