Crop
rotation

 

Every day we think
more about our earth, how to protect our environment, live healthy and still lose
nothing while trying to reach that. Soil erosion and pollution is one of the
environmental problems that we are facing today and the main reason for that is
irresponsible agricultural activities. Crop rotation can help not only to deal
with this problem but also to save money.

What is crop rotation?

Crop rotation is
the systematic planting of different specific crop in a special order for
several years in the same field. When
one vegetable is grown in one field for many years, it takes certain nutrients
from the soil and lack of soil nutrition leads to poor plant health and lower
yield. This process helps maintain nutrients in the soil, reduce soil
erosion, and prevents plant diseases and pests. Rotation schedule and plant
types depends on soil type, climate and resources. Rotation time also depends
from different plants, soil needs and farmer1.

Crop rotation helps to keep soil nutrition balanced. Rotation
between heavy nitrogen using a plant (such as Maize) and a nitrogen depositing
plant (e.g. Soybean) can help maintain a healthy soil balance2.

Also crop rotation prevents plants diseases, pests by
mixing crops that may be more subjective to some diseases or pests to the one
that is not subjective. For example, although corn is affected by corn
rootworms, soybeans are not. The soybeans help suppress the pest so that the
corn planted the following year will not be as adversely affected by it3

By the way crop rotation is really important to
organic farming and gardens as it helps to reduce the amount of fertilizers or
pesticides.

Crop rotation – Greening in Lithuania

Crop rotation is a
big part of agriculture in Lithuania. It’s used by small farmers in villages,
by amateurs and by professional farmers. From 2013 ‘Greening’ project was
initiated by EU so that farmers that adopt and maintain farming practices that
help meet environment and climate goals can benefit financially.

How does greening work?

Green direct
payments account for 30% of EU countries’ direct payment budgets. Farmers
receiving an area-based payment have to make use of various straightforward,
non-contractual practices that benefit the environment and the climate. These
require action each year4.
They include:

·      
diversifying
crops

·      
maintaining
permanent grassland

·      
dedicating
5% of arable land to ‘ecologically beneficial elements’ (‘ecological focus
areas’).

Crop
diversification requirement is for farmers with over 10 ha of working land.

If farmer has not
more than 30 ha he has to grow at least 2 crops and the main crop cannot cover
more than 75% of the land. And if more than 30 ha farmers have to grow at least
3 crops, the main crop covering at most 75% of the land and the 2 main crops at
most 95%5.

Problem and solution

Soil erosion and
pollution

Soil erosion is
the displacement of the upper layer of soil, one form of soil degradation. A
low level of erosion of soil is a naturally occurring process on all land, but
soil erosion is increased by using chemical and synthetic fertilizers. Fertilizers
also pollute soil and water. Planting the same crops every year or doing crop
rotation incorrectly increases soil erosion and depletion of nutrients6.

Solution:

Crop rotation is a
good solution for soil pollution and erosion because it can fix and help with:

·       Soil
organic matter;

·       Carbon
sequestration;

·       Nitrogen
fixing;

·       Pathogen
and pest control;

·       Weed
management;

·       Preventing
soil erosion;

·       Biodiversity;

·       Farm
productivity;

·       Risk
management.

Stake
Holders

·       Farmers;

Saves money for fertilizersa and pesticides. Produce
more healthy food. Maybe earn less money if crop rotation will be made
unprofesionaly.

·       Manufacturers;

If corp rotation will be made unprofesionalyy it can
affect the yield and then the amount of crops they will have to process. They
will also earn less if rotation will be unsucesfull.

·       Production
users;

Some users prefer Eco-riendly products;

Price can get higher if rotation won’t be succesful;

Naturally grown products are essential for healthy
lifestyle whitc is quite popular nowdays.

·       Environment
protection agencies;

Crop rotation is enviroment friendly process so they
will be happy with that.

·       Investors;

Crop rotation can be risky if done without certain
knowledge so investors can consider not to invest or invest less with more
severe rules.

·       Country;

Economic growth can slughtly differ depending on arm
profits;

Safe and protected enviroment is an important matter
for every country.

Swot

Strengths

·       Environment-friendly;

·       No
need to spend money on fertilizers;

Opportunities

·       Increased
farm productivity;

·       Organic
farming;

Threads

·       Less
yield because of unprofessional rotation;

·       Financial
risks;

Weaknesses

·       Takes
time and knowledge to improve land fertility and balance; 3,6%
Farms in 2015 were not suitable for ‘Greening’ benefits and just 2,69 % in
2017.

Results
and future actions

Results concerning greening in Lithuania

About 3.6% of farms in 2015 didnt fit to get greening
benefits and only 2.69% in 2017. In
2017 there were two times less Farms that didn’t match both ‘ecologically
beneficial elements’ and crop diversification requirements (138 in 2016 and 76
in 2017)7.
