Causes of decline
The 'modernisation' of our agriculture underlies this substantial decrease of nutrients in our fruit and vegetables.
The intensive agriculture has, over time, led to the bottom arm of nutrients.
With the help of fertiliser It tries to maintain production in spite of the exhausted soil.
But the limited composition of fertilisers does not allow the soil to recover sufficiently, which results in crops do not contain all the necessary nutrients have at their disposal.
As a result, the crops not really healthyas a result of which they fungi, insects and other (un)pests attract.
To combat them plant protection products such as pesticides, insecticides and fungicides.
