farming flaws?
im doing a hydroponic project for school and im doing the pros and cons at the moment
can anyone think of some flaws or problems with current day agriculture?
Look up the book “Hydroponic Food Production” by Howard Resh. This is probably one of the most comprehensive books on hydroponics written. The first couple of chapters covers your question throughly.
If you are going to compare Field Agriculture to Hydroponics you are going to have to clarify a few points. First, not all hydroponic systems are created equally. For instance, compare open circuit (use the water once and dump it) to recirculating (use the water over and over) systems. Both have ups and downs (mostly resource conservation vs. disease control). Second, when you mention hydroponics, I’m thinking mostly vegetable and small fruit production. Grain crops just can’t compete in hydroponics versus field production.
Let me hit some high-points of hydroponics over field:
1. Field production takes lots of space and requires the best soils.
2. Field ag = soil erosion, pesticide use, and large amounts of fertilizer and irrigation water in some areas. (There are actually four points there!)
3. Best soils for production are often not near population centers leading to higher transportation costs and lower freshness.
4. Field production is subject to the elements (frost, drought, cold spells).
Keep in mind that there are a lot of different hydroponic systems out there and some do a better job of addressing the faults of field production then others.
And keep in mind that hydroponics has its share of faults as well:
1. Cost of production is often higher.
2. It takes a lot more technical knowledge to run a greenhouse (higher skilled workers).
3. Disease control is critical.
4. Start-up costs are really high.
