• bio-intensive gardening


  meaning of BIG
• form of farming in which a small land area is intensively cultivated using available farm resources

  BIG
• organic agricultural system that focuses on achieving maximum yields from a minimium area of land while simultaneously increasing biodiversity and sustaining the fertility of the soil

  bio-intensive agriculture
• This allows water conservation compost within the bed allows for better absorption and storage of water

  Deep bed preparation
• ( t or f ) well established bed and cropping system can reduce water use by 66%


  t
• maximizes the use of plant and animal residues and wastes

  Nutrient recycling
• food of soil microorganisms, improving soil structure, good habitat for different microbes, different crop (minimize dominance but rather go for balance)

  Building up of soil’s biological base or OM
• relate to pest mgt, nutrient mgt, biodiversity and plant genetic conservation, improved nutrition-quality of produce, diverse income generation, vegetable is available year round.

  Diversified cropping
• difference of BIG from conventional gardening system

  use of locally adapted varieties
• (t or f) BIG uses 40-60% less purchased nutrients

  f (50-100%)
• (t or f) BIG uses 94-99% less energy while producing substantially increased yield, and increased soil fertility 


  t
• this orientation avoid shading crops by trellis

  E-W
• a downscaled version of BIG or a micro model of farming where a family unit or household is producing fruits and vegetables in special containers for personal consumption to help improve this income, health and well being of its family members.

  container gardening
• what is EPP by Dr. Ed Paningbatan

  Enriched Plotting Preparation
• by prof bong salazar garden

  windowsill micro garden
• a technique of growing different kinds of vegetables and other crops that uses minimal space, growing media and other materials which could be readily available

  Square foot gardening
• a well suited practical gardening in the urban areas whereby plants are grown in a vertically suspended panel.

  vertical garden
• higher water content, lower calorie content


  true
• what vitamin causes poor growth

  A
• a soluble form of fiber

  betaglucan
• antioxidant compounds in cruciferous vegetables are believe to inhibit the DNA damage that triggers some froms of cancer. what chemical groups are?


  indoles and isothiocyanates
• example of crop plant that is rich in soluble fiber which may help regulate blood sugar

  broccoli
• found in soya those may help against heart disease and possibly breast cancer

  isoflavones
• carbohydrate molecules abundant in plant

  saponins
• what color is the ideal in soil mixture

  dark brown
• ideal growing medium is a mixture

  3 part loam soil, 1 part compost
• a lowcost hydrophonics stystem for soil less vegetables

  hydrophonics
• two probable scenarios in establishing crop production enterprise

  1. the site known, suitable crops identified
  2. crops suitable, location selected
• the process of describing biological, physical, bio, socio economic environment

  site characterization
• analytical assessment 


  evaluation
• elements of site characterization

  biological, physical, socio economic
• the most unfavorable quality determines the suitability classification

  the limiting condition principle
• suitability classes are raised or lowered on the basis of

  judgements of the importance of different factors. Because subjective assessments are risky, the

  relevant factors are weighted, and account is taken of special limitations that may occur if two or

  more negative factors occur together

  the subjective assessment principle
• the fact that each land quality has an independent influence on suitability means that land qualities can be assigned values and manipulated arithmetically to

  provide a numerical assessment of overall suitability.

  the principle of arithmetic modelling
• characterization that means that the land characteristics have none to minor limitations which do not significantly reduce the productivity or yield of most crops.

  prime agricultural lands
• classified areas which have major limitations in

  topography, soil depth, rainfall, etc. These soils may also have low to very low fertility and have a

  suitability rating of S3.

  marginal agricultural lands
• have characteristics that cannot be

  readily corrected such as topography and soil depth. These areas can be upland soils located in

  rolling to hilly mountainous areas. These areas have suitability rating of N1 and N2.

  lands with severe limitations
• mechanical manipulation of the soil resulting to soil tilth favorable for seed germination and plant growth

  tillage
• usually done to break the soil compaction resulting into soil clods. It is more aggressive and deeper operation consequently leaving the soil rough. Plowing is a primary tillage operation


  primary tillage
• conducted after the primary tillage to reduce the soil aggregates and level the soil surface. Operations involve are harrowing and furrowing

  secondary tillage
