Gardeners Growing Media Conference

Some 65 gardeners many representing plant societies  ,parks and allotment associations met at STC on Thursday 16 th Feb (Click Here to view the agenda)

 

Judging from emails and personal conversations the speakers and subject matter were given the thumbs up with requests for further events .

 

Comments in the final open forum were that the information that they were receiving in gardening press  did not match that they had received from the experts on the day . In other words there was spin in the peat debate from all fractions, and it was difficult to assess why they could not buy reliable products and why they were being painted as the leading environment damagers  .

Pleas were made for much more information on the packs of compost although Christine Walkden did extract ,doing her talk ,admissions that many gardeners did not read the instructions . Basically they assumed because of the PR that the new composts would behave like peat  and they were not prewarned of the new skills required . Julian Davies reported from his many years trialling that nutrition was a greater problem than watering, and in particular composts based on green compost and to some extend wood residues needed to be freshly made , as the continuing composting process during distribution chain wrapped up the nitrogen . He warned about buying  wet and heavy bags and he preferred garden centres where composts were stored under cover . There were questions on how gardeners could contact Defra to express their views on Government Policy .

Greenhouse Gas Emissions /energy and biodiversity

Tuomisto H L, Hodge I D, Riordan P and Macdonald D W (2012). Comparing energy balances, greenhouse gas balances and biodiversity impacts of contrasting farming systems with alternative land uses, Agricultural Systems 108 (2012) 42–49

Conclusions  Even though the conventional systems had the highest energy inputs and GHG emissions per food product output, the whole farm energy and GHG balances were far more favourable for the conventional systems compared to the organic systems once the availability of extra land was taken into account. The results also suggest that integrated farming systems that use the best practices for producing high yields while using environmentally beneficial farming practices can lead to more favourable whole farm energy and GHG balances and the lowest negative impacts on biodiversity compared to organic and conventional systems.

 

I think its called sustainable intensification !!

Hedgerows provide corridors for foraging bumblebees

Researchers at the University of Northampton have published research on how bees use hedgerows to search for nectar-rich flowers.

Read an article in the Guardian about the research here. The original article in the scientific journal Oikos can also be found here.

STC currently have a pilot project looking at adding value to hedgrows and other farming landscape features by sowing wildflowers and shrubs along the hedge base. Stc are also looking at choosing tree and hedgrow species to provide nectar and pollen for bees during their entire active season.
