Glossary
Competition is a condition where there is a suppression of one organism as two species struggle for limiting
quantities of nutrients, oxygen, or other common requirements.
Compost tea is a concentrated microbial solution (‘brew’) produced by extracting beneficial microbes from
compost. Aside from providing direct nutrition, it also makes available microbial functions, such as
competing with disease-causing microbes, degrading toxic pesticides and other chemicals, producing
plant growth hormones, mineralizing plant available nutrients, fixing nitrogen and beneficial microbes,
leaving no room for pathogens to infect plant surfaces. It is applied much like a fungicide, to control
target plant pathogens.
Composting refers to a process involving breakdown of organic materials through action of decomposers
(e.g., microorganisms and macro-organisms) to form small bits of organic matter called compost.
Consumers’ guarantee refers to an organic guarantee system which involves groups or organized consumers
(e.g., Altertrade in Negros Occidental) who certify and buy organic products (e.g., banana) of known
producers. The major activities in a consumers’ guarantee program are: standard setting, inspection,
and certification.
Content refers to subject matters or topics taken up in an activity or activities to attain objectives.
Contour planting or farming refers to a method of farming where cultivation is accomplished by plowing
across slope following contour lines rather than up and down.
Cost and return analysis is an analysis of production cost relative to net return in an enterprise. Usually, the
lower the cost of production, the higher is the net return for a particular enterprise.
Cost of production refers to amount of labor, power, and material input costs in each operation for every enterprise.
Critiquing is an activity to assess progress and effectiveness of learning in terms of learning processes,
relationships, physical environment, and problems and issues relevant to learning as expressed by
participants.
Crop residue-inhabiting pests refer to all pests whose main harborage or habitat, in the absence of a suitable
host, is crop residue, such as weeds or any plant debris often left in the field after harvest.
Crop diversification refers to the planting at the same time in on-farm or field of as many crops to maximize
land uses and minimize pest and disease occurrence depending on such factors as crop preference,
technical knowledge, adaptability, market demands, and profitability.
Cross-pollinating vegetables are vegetables wherein pods or fruit setting result from union of female (ovule)
and male (pollen) reproductive cells of two different plants, varieties, or cultivars.
Crop rotation refers to the growing of two or more crops after another in a regular succession for two or more
years with an idea that a crop susceptible to a pest or disease is followed by a resistant crop or combined
in simultaneous cropping with other crops.
