Lynn Brakke Organic Farm


Please answer the following questions based on your visit to the Lynn Brakke Organic Farm and the article "What is Organic Food and Why Should I Care?"

1. How is organic farming different from conventional farming?

First, organic food is defined strictly by Federal law. And the farming process, field and fork are regulated through an extensive certification process.

Second, organic farming responds specifically to site conditions.

Finally, organic farming combines a lot of areas together, such as cultural, biological, and mechanical practices. And it is environmentally friendly because it can help cycle resources, promote ecological balance and conserve biodiversity.

 

 2. What is the nutrition value of organic food? Provide examples from the article.

The nutrition value of organic food is much higher than other conventional food. For example, women eating organic products were found to have around 50% higher levels of rumenic acid in their breast milk. UC Davis researchers found that the content of flavonoids in organic tomatoes were 79%-90% higher than normal tomatoes. Scientists realized that organic brands of catsup have 57% higher levels of antioxidant lycopene.  



3. How do organic practices improve the soil quality?

Organic practices improve the soil quality by the use of “manure and cover crops more than offet losses from tillage”.



4. Why is organic production expensive?

It costs a lot to foster organic food. The special knowledge of organic farmers is required. The fostering process and the limited quantity of planting are also the reason why organic production is much more expensive.
